Postdoctoral Research Assistant
I am a Postdoctoral Research Assistant in the Lyles School of Civil Engineering, jointly affiliated as a Visiting Scholar with the School of Industrial Engineering at Purdue University. My postdoctoral research builds upon my PhD work and is funded by the NSF. My research interests are centered on developing algorithms and risk-informed decision models to investigate the complex interplay between the human and socio-technical systems under the influence of various external stressors. My current research projects focus on modeling the complex climate-energy demand nexus and studying the climatic shocks to the electric power grid, with a broader objective to ensure a resilient and sustainable energy infrastructure systems.

Benjamin Rachunok

Benjamin Rachunok
PhD student
I am a first year PhD student in the Purdue School of Industrial Engineering. My current research interests revolve around using mathematical and statistical models to aid in the development of sustainable critical infrastructure. Originally from North Carolina, I graduated with a BS in Industrial and Systems Engineering from North Carolina State University in 2016. While at NCSU, my research focused on the use of alternative transportation in emergency medicine. While not in school, I am an avid runner and rock climber. Read more:

Deb Maia Silva
PhD student
I am a Civil Engineer in my first year as PhD student in the Environmental and Ecological Engineering Department. I graduated from the University of Campinas, Brazil, in 2016, and worked as a civil engineer from 2014 to 2016. Research interests are Data Analysis and Predictive Modeling. When not buried under giant databases, I will probably be orbiting around a ball at CoRec as the big sports fan I am.

PhD student
I am a PhD student in the Ecological Science and Engineering interdisciplinary graduate program and the Division of Environmental and Ecological Engineering. My research focuses on modeling the urban water-energy-climate nexus using multivariate statistical models. Ultimately, I would like to use my model to promote water sustainability in urban areas. I graduated from Ohio State University with a BS in Environmental Engineering in 2015 and have since worked as a research assistant on a variety of drought-related projects at Purdue. Outside of research, I enjoy reading novels, exploring new cities and spending as much time as possible by the ocean. ‚Äč
