From classic Newtonian dynamics to quantum mechanics, Department of Physics courses cover the range of laws that govern our universe, and how to apply them. Students will put their knowledge to use with circuit work, acoustics and sound generation, dynamic modeling techniques, and even physics for animation. Faculty experience ranges all the way from astrophysics to computational physics simulation.

Her research interests include atmospheric electricity and lightning, the global atmospheric circuit, passive microwave remote sensing, and tropical cyclones.

Dr. Solorzano publishes her work in journals such as Atmospheric Environment, Atmospheric Research, Eos (Earth and Space Science News), and Geophysical Research Letters. She often gives invited and contributed presentations at meetings, including the American Meteorological Society Annual Meeting, the IEEE International Geoscience and Remote Sensing Symposium, the Asia Oceania Geosciences Society Annual Meeting, and the American Geophysical Union Fall Meeting. She is a steering committee member of the atmospheric electricity section of the American Meteorological Society. In 2008, along with Jeremy Thomas, she was recipient of a Science and Math Improvement Grant from the Toshiba America Foundation. In 2017, they received the Amazon Catalyst Award of Merit, along with BS in Computer Science graduate Connor Bracy and Professor Robert Holzworth from the University of Washington. The project, a real-time tropical cyclone and lightning database, can be found at: In the same year, Thomas and Solorzano were also awarded a National Science Foundation grant for the project “Collaborative Research: Balloon Campaign to Quantify Thunderstorm Effects on the Global Electric Circuit.”

At DigiPen, Dr. Solorzano is the chair of the Physics Department, chair of the Diversity Committee, and a member of the Faculty Senate Steering Committee. Her teaching philosophy is geared towards experiential learning, engaging students in critical thinking, and encouraging students to take ownership of their education. She also believes that cultural, economic, and social diversity enhance the learning environment, and she is committed to increasing the diversity of students and faculty.

DigiPen Faculty Erik Mohrmann, Ph.D.

Erik Mohrmann, Ph.D.

Dean of Faculty

Dr. Erik Mohrmann studied psychology and physics at Rensselaer Polytechnic Institute in Troy, NY. He then moved to Seattle and earned his doctorate in physics at the University of Washington. He thoroughly enjoyed teaching at both institutions and has continued his teaching career at DigiPen Institute of Technology.

Mohrmann’s academic interests include learning models, the biological basis of behavior, nuclear astrophysics, and computational physics simulation, with most of his research in the latter two areas. His current research interests include stellar nuclear reactions and the modeling of deformable bodies.

Professor Mohrmann believes it is of critical importance to make topics pertinent, comprehensible, and interesting to each specific audience, because physicists, engineers, and artists all approach topics from different angles. His research helps him relate classroom physics to the world we all experience every day, and provides guidance to undergraduates and graduates who are researching topics in simulation.

DigiPen Faculty Abhay Shah, Ph.D.

Abhay Shah, Ph.D.

Assistant Professor

After completing his bachelor’s degree in Physics from Mumbai University (D. G. Ruparel College) in 2005, Dr. Abhay Shah moved to the U.S. and received his PhD in Physics at the University of Wisconsin-Milwaukee in 2011. As a graduate student, he worked on the self-force formalism that is used in modeling Extreme-Mass-Ratio Inspirals (EMRIs), two black holes inspiralling each other such that one of the black holes is roughly a hundred thousand times heavier than the other. (Such systems are located at the center of galaxies in which a stellar-mass compact object orbits a super-massive black hole. Gravitational waves emitted from EMRIs shed light on the strong-field spacetime structure of black holes, and help us understand the evolution of super-massive black holes.)

Upon completion of his PhD, Dr. Shah joined the Weizmann Institute of Science in Israel as a postdoctoral fellow from 2011 to 2013. During this time, his interests evolved into an overlap between two formalisms used to study EMRIs: the self-force formalism and the post-Newtonian theory, two different approximations of Einstein’s General Theory of Relativity. Along with his collaborators, he was able to extract very high-order linear-in-mass-ratio post-Newtonian corrections using analytical solutions, which allowed him to push the accuracy of his numerical calculations to arbitrary precision and extract analytical coefficients from numerics using experimental mathematics techniques.

From 2013 to 2017, Dr. Shah was a Research Fellow at the University of Southampton, UK. While there, he continued his work on EMRIs using the different formalisms as well as experimental mathematic techniques. He also developed an interest in black hole perturbation theory, which led him to work on finding new gauge-invariants and the equations they might satisfy.

Apart from research, Dr. Shah is passionate about teaching at both the graduate and undergraduate levels. He believes that physics, a basic requirement of all engineering and technical disciplines, is one of the many subjects that will churn students’ brain-wheels by demanding critical thinking and analytical reasoning, helping them in any career they pursue. He encourages students to be equal and active partners in the learning process. He serves as a referee for Physical Review D, Physical Review Letters, and Reviews of Modern Physics, and in his spare time pursues his interest in machine learning.

DigiPen Faculty Anand Thirumalai, Ph.D.

Anand Thirumalai, Ph.D.

Assistant Professor

Anand Thirumalai earned his bachelor’s degree in materials engineering from the Indian Institute of Technology (IIT) in Roorkee, India. He then went on to earn a master’s degree in materials engineering from the University of British Columbia (UBC). For his master’s thesis he worked on designing and characterizing new-generation turbine blade materials, made of nickel-based superalloys.

After getting his master’s degree, he switched fields completely to follow his passion and scientific curiosity — astrophysics. For his second master’s degree at UBC, this time in astrophysics, he worked on studying the strongest magnetic fields in the known universe — those found in neutron stars — and computing the structure of atoms in such field strengths.

Later, his Ph.D. work looked at the end stages of stellar evolution. He developed a novel stellar wind model combining magnetohydrodynamics with particulate dust-dynamics and stellar rotation. His wind model is applicable to a range of stellar masses and stellar sub-types and presents a route for solving the so-called missing mass-loss mechanism problem in certain types of evolved stars.

Before coming to DigiPen, Dr. Thirumalai was also a School of Earth and Space Exploration Postdoctoral Fellow at Arizona State University. His research there involved studying winds of evolved stars as well as research in computational atomic structure. He has developed some of the fastest and most accurate atomic structure software for atoms in strong magnetic fields. He continues this research work in collaboration with researchers at UBC in Vancouver, as well as with researchers at the University of Oslo in Norway. His research these days focuses on making headway in the almost completely uncharted field of atomic and molecular structure in strong magnetic fields, as well simulations of star and planet formation. A large part of his current research focus involves harnessing the immense computing power of GPUs in astrophysical simulations.

Dr. Thirumalai teaches at all levels of the physics curriculum at DigiPen and believes in promoting diversity and inclusivity in the classroom, placing an emphasis on both teamwork as well as an interdisciplinary approach for solving modern problems using modern methods of solution.
