Engineering Research Projects
- Project 1: Biomechanical Responses during Pre-Crash Maneuvers and Autonomous Driving Scenarios
Mentor: Valentina Graci, PhD
Motor vehicle crashes remain a leading cause of death for children, youth, and young adults. Historically, automotive safety research and advancements have focused on the mitigation of injuries once the crash has occurred. However, more recently automotive safety research is shifting its focus to studying events prior to the crash. Previous research has shown that more than 60% of crashes involve some form of pre-crash maneuver (braking, swerving, skidding) prior to the crash. This number is likely to increase with the advent of early warning systems and autonomous vehicles. At the Center for Injury Research and Prevention, we are interested in understanding how pre-crash maneuvers affect child occupant position and motion prior to a crash. We are developing warning systems that could decrease reaction time and body motion outside the optimal position within a seat belt. We are also developing new technology and analytic methods to test seating configuration and automatic emergency braking in critical autonomous scenarios.
REU Project Description
The REU student will become a member of the Engineering Research Core at the Center for Injury Research and Prevention and will receive mentorship from several of the lead investigators of the Core. Depending on the stages of projects, the student will be involved in various aspects of the research process, including designing and machining experimental fixture, data collection on human volunteers, post-processing, data analysis, and interpretation of the results. The student will develop skills with data analysis of a diverse set of data types that could potentially be: motion capture and EMG data collection and/or analysis of children and young adults. Previous experience using MATLAB is critical. The student will have the opportunity to increase skills in this area. The student will also gain experience in problem-solving, analyzing data, interpreting findings, and developing new research ideas. There may also be potential opportunities to submit and present the student's work at conferences and to participate in the preparation of journal publications. This project work is in person to allow the student to also participate in potential data collection or fixture modifications, besides data analysis.
- Project 2: Understanding Eye-Glance Behaviors Among Young Drivers
Mentor: Thomas Seacrist, MS
Despite continued advances in young driving safety, motor vehicle crashes remain a leading cause of death for young drivers (16-24 years). While inexperience contributes to this elevated crash risk, other developmental factors, such executive function, also influence crash risk in young drivers. Our previous research has shown that drivers who are slower to develop their executive functioning skills are more likely to be involved in motor vehicle crashes. Additionally, drivers with poorer executive functioning are less likely to detect road hazards. Our team is currently collecting eye-tracking data among novice drivers using a novel simulated driving assessment. We are interested in understanding how eye-glance behaviors vary with executive function and other development factors.
Additionally, we are also interested in understanding how eye-glance behaviors vary among young drivers during their typical day-to-day driving. Recently, the US Department of Transportation funded a large-scale US naturalistic driving study – the Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study – which tracked day-to-day driving among 3,000 drivers over a three-year period. This large dataset offers a unique opportunity to study eye-glance behavior during real-world driving. We are interested in understanding how eye-glance behavior varies with driver age, road types, environmental factors, etc.
REU Project Description
The REU student will become a member of the Neuroscience of Driving Team at the Center for Injury Research and Prevention and will receive mentorship from several of the lead investigators. The REU student will be involved in the review and analysis of eye-tracking data collected from young drivers during simulated driving assessment (i.e. a virtual drive consisting of common crash scenarios) and/or during real-world driving (i.e. eye-tracking data collected from in-vehicle cameras that tracked drivers during day-to-day driving). The student will hone his/her skills with video coding, eye-tracking metrics, data analysis, and team-based data review. The student will also gain experience in problem-solving, interpreting findings, and identifying new research questions. There will also be opportunities to submit and present at conferences and to participate in the preparation of journal publications.
To this end, we are seeking a highly motivated applicant with a strong interest in eye-tracking, traffic safety, and/or human factors, ranging from conceptualization of research projects to publication. Students majoring/concentrating in Engineering, Data Science, Human Factors, Behavioral Science, or a related major are encouraged to apply. Previous experience using MATLAB, Python, R, or other programming language is required, and the student will have the opportunity to develop skills in this area. Prior experience with video coding or eye-tracking is preferred. Scientific writing experience and an interest in co-authoring publications is also preferred.
- Project 3: Analysis of Pediatric Occupant Kinematics and Kinetics in Motor Vehicle Crashes (In-Person or Remote)
Mentor: Jalaj Maheshwari, MSE
Motor vehicle crashes and incidents are a leading cause of injury for children, youth, and young adults worldwide. The Engineering team at the Center for Injury Research and Prevention strives to prevent these motor vehicle injuries through a variety of pediatric research projects using computational modeling and/or sled testing. Human body models and anthropomorphic test devices (ATDs), also known as crash test dummies, are a great tool to assess the kinematic and kinetic responses of an occupant under different crash conditions. We are analyzing the responses of pediatric occupants in different crash conditions, vehicle restraint parameters, and child restraints. The occupant kinematics, kinetics, and injury metric data will be analyzed over the crash conditions to better guide passive safety systems (seat belts, airbags) and child restraint system development.

The student will be involved in various aspects of the research process including data extraction, data pre-processing, data analysis, and interpretation of the results. The student will be analyzing kinematic, kinetic, and injury data.
Previous experience using MATLAB and/or Python is required. Additional experience with finite element (FE) modeling is desirable but not required. The student will have the opportunity to increase skills in these areas. The student will also gain experience in problem-solving, data analysis, interpreting findings, and developing new research ideas. There will also be opportunities to submit and present the student's work at conferences and to participate in the preparation of journal publications.
- Project 4: Social Equity and Spatial Effects on Safe Mobility
Mentor: Megan S. Ryerson, PhD
The field of transportation recognizes that the “after-the-fact” crash-based model of safety is biased, but presently does not have a clear mechanism to test safety in an a priori manner. Earlier attempts to collect such proactive data have been challenging and prohibitively expensive, or, at worst, unsafe. However, a new individual-level data set of virtual driving assessment scores, merged with real driving test results and traffic infringement and crash records obtained from administrative sources, affords a unique opportunity to begin proactively planning for safe mobility.
At the Center for Safe Mobility at the University of Pennsylvania we are particularly interested in working with these data to measure the social and spatial predictors of safe mobility. In this study we operationalize safe mobility through virtual driving assessment results, live driving test results, and observed driving behavior. We will then measure the effect of socioeconomic and demographic predictors on these indicators using measures such as: the individual’s socioeconomic and demographic background, roadway typologies around the individual’s residence, intersection characteristics at the location of low-test performance or an observed crash, and more. The Center for Safety Mobility features a diverse and interdisciplinary research team from fields that include engineering, city planning, spatial science, and more.
REU Project Description
The REU student will be a member of the research team at the Center for Safe Mobility and will receive direct mentorship from Dr. Ryerson and lead members of her research team. The student will engage in a diverse array of research tasks including, but not limited to: data analysis, data visualization, writing and oral presentation, and spatial analysis. The Center for Safe Mobility conducts almost all analyses using the open-source statistical software R. Previous experience using R is thus desirable. Regardless of knowledge of R, the student will have ample opportunity to increase skills in this platform, given the wide range of uses for which it is currently employed in the Center’s research.
The student will also be an active intellectual partner and contribute in regular meetings with the research team, actively contribute to project development, and help generate new research questions. There will be possible opportunities to present the student's work at conferences and to be co-author on journal publications.
- Project 5: Developing 3D-Printed Anthropomorphic Models to Improve Clinical Training
Mentor: Michael Hast, PhD and Elizabeth Silvestro, MSE
Knee injuries are a common complaint among children presenting to emergency rooms and primary care centers. A common sign of knee injury is effusion, a collection of fluid that can be encapsulated or burst. Current diagnosis begins with a physical exam, which relies on a subjective interpretation of manual examinations. Medical training programs provide minimal guidance with respect to accurately diagnosing pediatric knee effusions. At the same time, a misdiagnosis or delay in identifying knee effusions can impart longstanding complications to the joint, including growth disruption and loss of range of motion.
Because of this, MRI and ultrasound are currently used to provide clarity to the diagnosis, but this represents a significant increase in time spent in the clinic and includes a significant economic burden. Therefore, there is a need for a scalable solution to adequately prepare clinicians for manual pediatric knee evaluation. Hands-on trainers revolutionized training in cardiopulmonary resuscitation and offer an effective framework for improving manual diagnosis of pediatric knee effusions. The goal of this project is to design and develop 3-D printed models of physiologic and pathologic pediatric knees for the purpose of training medical professionals.

- Project 9: Cognitive and Circuit Impairments Induced by Mild Traumatic Brain Injury
Mentor: Akiva Cohen, PhD
Traumatic brain injury (TBI) is the leading cause of death and disability in children and young adults. A TBI occurs on average every 21 seconds and afflicts approximately two million people annually in the United States. No effective therapy currently exists to treat TBI. A profound obstacle to the diagnosis and treatment of TBI is the absence of an objective, quantitative test for TBI. The difficulty in diagnosing TBI is due in large part to the overlap in symptoms between TBI and other conditions (e.g. stroke, migraine, PTSD, depression and non-convulsive seizures), as well as variability in the initial injury and clinical presentation. Therefore, we are determining the nature of a brain circuitry functional biomarker in mice that have received a mild TBI.
REU Project Description
The REU student will become a member of the Cohen Lab at the Children’s Hospital of Philadelphia Research Institute. The student will receive mentorship from the lead investigator, as well as from members of his laboratory. The student will learn various behavioral paradigms and immunohistochemistry, as well as cell counting and biochemistry. The student will also gain experience in problem-solving, data analysis, interpreting findings, and developing new research ideas. There will also be opportunities to submit and present the student's work at conferences and to participate in the preparation of journal publications.
