Michalek interviewed on The Why
EPP’s/MechE’s Jeremy Michalek spoke with The Why news program about how environmentally friendly electric vehicles are. “Electric vehicles are one of the few ways that we have to move people and goods with very low emissions. The emissions that we get depend on how we charge the vehicle, [and] what energy we use to produce the electricity to charge the vehicle, but it’s at least possible to generate electricity with very clean sources and end up with a big improvement.”
MechE’s Eni Halilaj was quoted by Reuters about humanoid robots. “Our body is a complex engineering system that we still do not fully understand,” Halilaj said. “We have a long way to go to reverse engineer it, making motion planning and control challenging for humanoid robotics.” Halilaj directs the Musculoskeletal Biomechanics Lab at Carnegie Mellon University.
MechE’s Abert Presto was quoted about air quality in the Allegheny Front’s article about residents’ concern over the new Shell ethane cracker in Beaver County. Presto’s research group has installed monitors near the cracker.
Johnson quoted in Reuters
MechE’s Aaron Johnson talked about the challenges of autonomous robotics in an article on Tesla’s new Optimus robot. Johnson explains why handling soft, unpredictable material is harder for a robot than for a human.
EPP/MechE’s Kate Whitefoot discussed future uptake of electric vehicles in Vox after California passed a measure banning the sale of fossil fuel-powered cars by 2035. “It is expected that EVs will dominate the new vehicle market nationwide in the future,” she told the outlet. “The uncertainty is exactly when this will occur. This regulation by California would serve to accelerate that timeline.”
MechE’s Venkat Viswanathan shared expert advice in GreenBiz on how climate tech startup founders can approach investors as the market shifts.
Research by MechE’s Shashank Sripad on battery-powered urban aircraft was referenced in a Fast Company story on building flying cars. Specifically, Sripad’s research looked at ways to improve energy efficiency. “Even though the battery safety brings in some issues, the rest of the aspects in terms of the number of critical points of failure and so on are a lot fewer,” he says.

EPP/MechE's Jeremy Michalek was quoted in MSN on the environmental impact of electric vehicles. As Michalek first told the New York Times, “If you’ve got electric cars in Pittsburgh that are being plugged in at night and leading nearby coal plants to burn more coal to charge them, then the climate benefits won’t be as great.”
Zhang delivers two keynotes
MechE’s Jessica Zhang recently delivered two virtual keynotes. One was at the 7th International Conference on Computational and Mathematical Biomedical Engineering (CMBE22) on June 27-29, and the other one was at CVPR 2022 Workshop and Challenges: Deep Learning for Geometric Computing on June 20.
Tucker to co-chair workshop on AI and justified confidence
National Academies of Sciences, Engineering, and Medicine

The kickoff meeting is Wednesday, June 29.
EPP/MechE’s Jeremy Michalek was quoted in a recent article on Marketplace on Electric Vehicles (EVs). Michalek was interviewed about his experience and expertise on the sparse infrastructure for EVs. He explains that if people are going to adopt EVs en masse they have to be able to travel with them and own them even if they live in an apartment. “If you don’t have off-street parking, you need to know that you are going to have access to public chargers and be able to reliably charge your vehicle,” Michalek said.
MechE’s Albert Presto was quoted in Fatherly on various air filtration systems to protect yourself from air pollution. “The better the filter, the faster it will get clogged, so it needs to get replaced more often than a filter that lets a lot of particles through,” Presto said. He explains that inside the home, a HEPA filter is the best air filtration system on the market. But it’s expensive and has to be replaced often. Presto explains that most air filters use the MERV system in which the higher the MERV number, the more efficient the device is at filtering particles out of the air, which is useful to check when buying air filters.

Michalek quoted on EVs
EPP/MechE’s Jeremy Michalek was quoted in Lifewire about new federal Electric Vehicle (EV) charging rules. These rules include new standards for the national EV charging network to homogenize the payment systems, pricing, charging speeds, and more. “For long-distance travel, a robust network of chargers along major routes, like highway rest stops, is needed,” Michalek said, “If the network is sized for ordinary days, there will be huge queues and massive wait times on peak travel days. If the network is sized for peak travel days, there will be a lot of investment in infrastructure that goes unused on most days.”
Zhang delivers lecture at ECCOMAS
ECCOMAS Congress 2022
MechE’s Jessica Zhang delivered a semi-plenary lecture at the 8th European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS Congress 2022) in Oslo, Norway on June 5-9, 2022.

EPP/MechE’s Katie Whitefoot was quoted in a Vox article for her expertise in electric vehicles in public policy. “Efficiency regulations are still really important even as automakers are making pledges to electrify their fleets,” Whitefoot said. The article describes the various hurdles in converting our U.S. car population to electric vehicles. The car industry moves slowly and no matter how fast we convert to electric vehicles it could still take decades to get gas-powered cars off the street since the average lifespan of a car is 11 years. Car companies are also less inclined to take risks as the economy falters. “Uncertainty in and of itself has a lot of impact on the industry in terms of long R&D planning,” Whitefoot explains.
Michalek quoted on school bus environmental impact
EPP/MechE’s Jeremy Michalek was quoted in Popular Science article about the new federal Clean School Bus Program. The program aims to replace diesel-powered school buses with electric buses over the next five years. “When diesel is burned in a bus engine, it produces fine particulate matter—particles with a diameter much smaller than human hair—that floats in the air and lodge deep in our lungs when we breathe them in,” Michalek said. He further explained the dangers of carbon pollution in an urban environment and also that electric buses are not “pollution-free” as it still pollutes the environment to produce the batteries for vehicles like these.
Yim and Johnson quoted on small robotics
MechE’s Aaron Johnson and Justin Yim were quoted in an IEEE Spectrum article highlighting their work in small humanoid robots. Their work was displayed at the IEEE International Conference on Robotics and Automation(ICRA). The presentation highlighted a 15-centimeter bipedal robot. “Our goal with this project is to make miniature walking robots, as small as a LEGO Minifigure (1-centimeter leg) or smaller.” said Yim. Johnson was quoted as saying, “Minimally actuated designs that leverage passive dynamics will be key. We aren't there yet on the LEGO scale, but with this paper, we wanted to understand the way this particular morphology walks before dealing with the smaller actuators and constraints.”
CMU team wins big at robotics conference
MechE’s Victoria Webster-Wood and her team took home top honors in the ICRA 2022 Outstanding Mechanisms and Design Paper category for their submission, “Design of a Biomimetic Tactile Sensor for Material Classification.”
Whitacre interviewed on environmentally friendly batteries
Instigators of Change
Scott Institute Director Jay Whitacre was interviewed in the podcast Instigators of Change on how batteries can still have a negative impact on the environment. He explained how, depending on where you are in the world, a hybrid vehicle might be a smarter choice than fully electric vehicles (EVs). The reason for this is a combination of factors from how the electricity for the EVs is generated to the fact that battery technology has not progressed past some major hurdles in its design since the 1990s. Whitacre points out that the batteries first used in Tesla cars were nearly identical to those developed in the late ’90s.
MechE’s Carmel Majidi was quoted in Lifewire on robotic hand manipulation about MIT’s new robotic hand that can manipulate over 2,000 different types of objects. “These hands are highly dexterous and capable of performing in-hand manipulation,” said Majidi. “That is, in addition to grasping and releasing objects, they can use their fingers to manipulate an object like a screwdriver or scissors.”
Majidi quoted on gallium in bendable electronics
MechE’s Carmel Majidi was quoted in Smithsonian Magazine ongallium’s use in wearable electronics. “You can use it to track your own body’s motion, or the forces that you’re in contact with, and then impart that information into whatever the virtual world is that you’re experiencing,” Majidi said. Wearable electronics is just one of many uses of gallium the article covers. Majidi discusses how the bending, crunching, and flexing of these gallium circuits “printed” onto the hand or circuit can change the current flowing through the circuit and therefore change the input to a computer tracking movement.

MechE’s Venkat Viswanathan was quoted by WIRED on his battery research, which focuses on electric vehicles. After a summer road tripping cross-country in an electric car, he began to consider a different application for his work. “I was like, ‘Wait, what am I doing with all these new batteries I’m inventing?’” Viswanathan recalls. “Who is going to need them?” There was another way to travel coast-to-coast, he realized, one that batteries were far from decarbonizing: flight.
Whitefoot quoted on electric vehicle industry
Detroit Free Press
EPP/MechE’s Kate Whitefoot was quoted by the Detroit Free Press on competition in the electric vehicle industry. Whitefoot said the top-selling EVs in the future will depend on how the batteries perform. So the companies that design and make the best batteries, win. “If you want to come in, like a Tesla, you have to know both sides of the business: How to make a great battery and also how to build vehicles. It’s not enough to do just one of those sides,” Whitefoot said. “Those companies that can build on expertise in both manufacturing and batteries will have a competitive edge.”
Michalek quoted on electric vehicle chargers
Detroit Free Press
EPP/MechE’s Jeremy Michalek was quoted by the Detroit Free Press about GM’s plan to install electric vehicle chargers at their worksites for free use by employees. “But there are a lot of households that rent or have off-street parking, so adopting EVs for those households is a harder sell,” Michalek said. “So if you have a stable job such as at General Motors, that charger at work might make a difference in your willingness to adopt.”
MechE’s Shawn Litster was interviewed in VeloNews on Zwift, the largest virtual cycling gaming program. Zwift hosts thousands of events, and its detailed customization menus, superior graphics, and in-game chatting, and in-game chatting make it a tough competitor. Litster believes that the program uses equations to calculate a user’s height, which is then applied to the virtual bicycle and used to calculate and model aerodynamic drag.
Engineering undergraduate alumni quoted on startup
MechE alumnus Alexander Baikovitz and ECE alumnus Haowen Shi were quoted by Technical.ly about their startup, Mach9 Robotics, which launched an initiative to assess Pittsburgh bridge infrastructure after the bridge collapse on January 28. The Pittsburgh Bridge Initiative, as the company is calling it, will involve a concerted program to map, monitor, and assess the approximately 450 bridges in the Pittsburgh region over the next year. “What we really want to be able to distinguish between is the difference between poor infrastructure and infrastructure that needs to be able to be shut down,” Baikovitz said.
LeDuc’s work on desalination featured in newsletter
MechE’s Phil LeDuc and alumnus Adam Wood’s work on using bread to remove salt from water was featured in Axios’ science newsletter on February 3. Under more controlled lab conditions, Wood found bread could be used to create electrodes. Whether the bread-based desalination approach could be used on a large scale is unclear.
Gomez interviewed on infrastructure
MechE’s Nestor Gomez was interviewed on the podcast Background Briefing on infrastructure after the bridge collapse in Pittsburgh. “A lot of these bridges will have to be replaced, and to be fair, we almost never build a bridge to last 100 years. If it does last 100 years, then we consider that a great success,” Gomez said. “But the lifespan of a bridge is maybe 50 or 60 years. [The Fern Hollow Bridge] probably had a few more years left in it, but corrosion and other kinds of damage wore it down. It was 52 years old.”
Litster quoted on hydrogen fuel cell market
MechE’s Shawn Litster was quoted in the Associated Press on the expansion of the hydrogen fuel cell market. General Motors recently announced that they will work with another company to use these fuel cells to build mobile electricity generators, electric vehicle charging stations, and power generators for military camps. However, GM is not the only company expanding this market. Litster explains that multiple companies, including AFC Energy in the United Kingdom, are selling or testing the products, opening up competition for the products.
Majidi mentioned on satellite robots
MechE’s Carmel Majidi was mentioned by SpaceRef.com about a CMU-headed consortium selected by the Air Force Research Laboratory and the Air Force Office of Scientific Research to pioneer research into robotic inspection, maintenance, and manufacturing of satellites and other structures while in orbit. CMU’s efforts will be led by Choset and Matt Travers, co-directors of the Robotics Institute’s Biorobotics Lab; and Majidi, who specializes in soft robotics. CMU will collaborate with researchers at the University of New Mexico, Texas A&M, and Northrop Grumman Corporation.
Zhao quoted on digital twins
MechE’s Ding Zhao was quoted by Time Magazine on digital twins, an exact digital re-creation of an object or environment. Zhao has been working with carmakers to use digital twins to improve the safety of self-driving vehicles. “Real-world testing is too expensive and sometimes not even effective,” Zhao says.
MechE’s Shawn Litster was mentioned by AP News about hydrogen generators entering the market. Multiple companies are selling or testing hydrogen generators, said Litster, who has studied hydrogen fuel cells for about two decades. There will be more demand for the generators as vehicles switch from internal combustion to electric power. Police departments and municipal governments, he said, will need backup power to charge emergency vehicles in case of a power outage. Hydrogen can be stored for long periods and used in emergency cases, he said.
Tucker named to U.S. Chamber of Commerce Commission

AI research featured in podcast
Featured on the Wevolver podcast The Next Byte, “Meet the AI Replacing Your Manager,” new research by MechE’s Chris McComb and Jon Cagan shows that AI may soon be taking over managerial positions—and doing a better job at them. Their study shows that in comparison to human counterparts, AI intervened less during projects. When given a certain number of interventions, not only did human managers use more than the AI, they used all of them. On the other hand, AI managers used only a few light directions. They also found that interventions done by human managers had a negative impact on production overall, while AI managers had an overall positive effect.
Humotech, originating from CMU’s Mechanical Engineering Department, develops tools for the advancement of wearable robotic control systems and other wearable devices. Using its own research community, Humotech will further build and support a development community around the open-source leg and seek to incorporate the leg into Humotech’s Caplex platform. Caplex is a hardware and software testbed that enables researchers to emulate the mechanics of wearable machines, including prostheses and exoskeletons.
MechE’s Venkat Viswanathan and Shashank Sripad were featured in Forbes for their research on eVTOLS. According to Viswanathan and Sripad, “A key problem for eVTOL aircraft is the weight of batteries, which contain 14 times less energy by weight than aviation fuel. To achieve their range and payload goals, Beta, Joby Aviation and Kitty Hawk appear to need battery packs with energy densities at the outer range of the newest technologies, while Lilium is way out in experimental territory.”
Viswanathan quoted on solid state batteries
MechE’s Venkat Viswanathan was quoted in Torque News on solid-states batteries, created by QuantumScape. Using a solid electrolyte instead of a liquid solution, solid-state batteries can store considerably more energy by weight and volume than lithium-ion batteries and will be especially useful for electric vehicles. Viswanathan emphasized the importance of this discovery: “… these results blow up what was previously thought possible in a solid-state battery. Withstanding a high enough current density to allow fast charging without forming dendrites has long been an industry holy grail.”
Michalek quoted on rechargeable electric vehicles
The New York Times
EPP/MechE’s Jeremy Michalek was quoted in The New York Times on charging solutions for electronic vehicles (EV). One of the biggest challenges facing the conversion of fossil fuel reliant vehicles to EVs is reliable charging. One solution could be inroad charging. Michalek explains, “To put this in context, inroad charging while driving is not likely to be a broad solution for all electric vehicles, but it could play an important role for some applications.” While this may not apply to residential vehicles, it could be promising for long-haul trucks and other commercial vehicles.
EPP/MechE’s Jeremy Michalek was quoted in Grist on travel and its effect on climate change. There are multiple variables that effect climate and travel, such as the age and model of one’s car, traffic, and distance. For Michalek, the difference lies is how you tackle these variables together. He said, “The more you accelerate really quickly and then come to a quick stop—that type of aggressive driving certainly consumes more energy,” also leading to more carbon emissions.
MechE’s Venkat Viswanathan was mentioned by Aionics, where he is a chief scientist, about his new work on using robotics and machine learning for the efficient optimization of a non-aqueous battery electrolyte. This announcement came during the Advanced Automotive Battery Conference, which was held December 7-9 in San Diego. Using this workflow, Viswanathan’s lab identified six fast-charging electrolytes in an amazingly rapid 42 experiments across two workdays. Compare that to 60 days using exhaustive searches of the 1000+ possible candidates.
