I am 3rd year PhD student working with professor Lyubov Titova in the Ultrafast THz and Optical Spectroscopy Lab. I study the optical properties of 2D materials for a wide range of applications such as THZ photonic devices, THz EMI shielding, optoelectronic devices, photo-electrochemistry, and photovoltaics. I specialize in many types of spectroscopy including Time-Resolve Photoluminescence, Time domain and Time resolve THZ spectroscopy, and Transient absorption. I also enjoy helping undergraduate students to master their experimental skills, and mentoring high school women and encourage them ...

Jacob Feinstein

I am a Physics Ph.D. student and WPI CEDAR fellow working with Professor Raisa Trubko in the WPI Quantum Sensing group. Using nitrogen-vacancy centers in diamond, this group works to image magnetic fields with high spatial resolution. We work towards developments of state-of-the-art quantum instruments as a tool to study the magnetic properties of novel materials and biological organisms. My current focus is to incorporate machine learning techniques to develop new data analysis methods in the lab.

Andrew Fitzgerald

I am a physics Ph.D. student working with Dr. Lyubov Titova. In my current research, I use ultrafast terahertz spectroscopy to measure the optical and electronic properties of novel 2D materials for applications in solar energy conversion, energy storage, and electromagnetic interference shielding. Additionally, I am a WPI CEDAR fellow. As a part of this program, I work with collaborators from WPI’s Data Science and Chemistry departments in order to produce research that will advance the circular economy for increased sustainability.

Peter Hedlesky

I am a PhD student working under Professor Doug Petkie where we are developing WPI's integrated photonics design, testing, and characterization capabilities. Our primary projects involve developing microring resonators or "microcombs" for DOD applications and working with our collaborators at AIM to develop a visible light silicon nitride platform. I was awarded both an AFRL scholars internship with the U.S. Space Force at Kirkland AFB and the DOD SMART fellowship at DTRA in 2022. I enjoy working with U.S. service men and women developing new technologies to keep them and the U.S. as a whole a ...

Norbert Hugger

I am focused on a collaboration between our Nuclear Science and Engineering Program and Westinghouse LLC to design a next generation University Research Reactor (URR) that can also provide a zero-emission source of energy to the campus. Funded by NRC, we are using a computation model to study the radiation fields produced by the eVinci 5MWe microreactor during operations. Using these models, we can design facilities and apparatus that are useful in a research and shielding that meets regulatory requirements. Of primary interest are thermal neutron columns for imaging and enhanced flux ex-core ...

Anna Mederer

I am a physics PhD student with a focus in Physics Education Research (PER). I am working with Prof. Ben Pollard to research the physics writing skills that undergraduate physics lab students need to create lab reports that are cohesive and engage with scientific literature. Starting in 2018, I worked for the Physics Department as an undergraduate Peer Learning Assistant and since 2021, I have been a graduate Teaching Assistant. My favorite part about working with students is seeing them expand their understanding by engaging in active learning and laboratory settings.

Holden Snyder

I am a PhD candidate and I work in David Medich’s lab performing resuspension experiments. Currently, my objective is to determine how changing the deposition surface affects the suspended fraction above the surface. I use europium oxide powder as a suspending mass and determine the amount of europium in the air by sampling the air, then performing neutron activation analysis on the air sampler filters. When I am not in the lab I enjoy hiking, climbing, video games, and underwater hockey.

Kevin Stern

I am a Physics Master's student researching efficient calculations of random walk lengths along the edges of symmetric polyhedra. From 2018 to 2021, I worked as a PLA in the Physics and Mathematical Sciences departments, and since 2021 I have worked as a GLA in the Mathematical Sciences department. In addition to my research and teaching, I am currently on a quest to complete all of Advent of Code.

Emily Sutherland

I am a physics PhD candidate working under Professor Aaron Deskins in the Chemical Engineering department. We use Density Functional Theory (DFT), which is essentially computational quantum mechanics, to study electronic and elastic properties of materials. In particular, we study a family of 2D materials called MXenes for use in applications such as photocatalysis, energy storage, and solar cells. This research is part of the WPI CEDAR program, connecting us with experimental physicists, data scientists, and materials scientists who also study MXenes.
