Prior to joining the Wooldridge Combustion group in 2015, Rachel received her BSc in Mechanical Engineering from the University of Cincinnati (2015) and worked in the Mechanical Engineering and Testing Division at the Lubrizol Corporation where she devoted significant time to research in engine lubrication and tribology while designing the next generation of bench top testing for simulating proper hydrodynamic lubrication regime changes experienced by the piston ring and cylinder bore tribocouple. Additionally, as an undergraduate, she had significant research experience in computational fluid dynamics and test rig design for validating CFD results in Aerospace applications. Rachel has also been involved in the Engineering Education Research community focusing on successfully developing outreach and mentoring programs for increasing college preparedness and success for students from underrepresented groups.

Ph.D. Students

 
  • Jongyoon Bae is a Ph.D. student in chemical engineering. He joined Goldsmith group in fall of 2017 and is also jointly advised by Prof. Andrew Peterson. He received his B.S.E. in Chemical Engineering from the University of Michigan in 2011 and received his M.S. in Chemical Engineering from Northwestern University in 2014. His master’s study research topic was surface hydrophobicity of metal oxides made by atomic layer deposition (ALD). From 2014 to 2017, he worked at Korea Research Institute of Chemical Technology (KRICT), a Korean national lab, as a researcher. His research topic at KRICT was heterogeneous catalytic conversion of various hydrocarbons including plasma-catalytic non-oxidative conversion of methane (NOCM) and hydrocracking of light cycle oil (LCO). At Brown, he continues to study NOCM with various computational methods.

 
  • Katrin Blondal joined the group in 2017 as a Ph.D. student in Chemical Engineering. She is from Reykjavik, Iceland where she received her B.Sc. in Chemical Engineering in Spring 2017 from the University of Iceland. Katrin is interested in energy conversion processes and sustainability. Her current research is in the field of computational catalysis. This work includes various computational calculations for contributing to the database of RMG-Cat, an open-source software that is used for generating microkinetic mechanisms for heterogeneous catalysis.

 
  • Aaron Danilack's hometown is Mountain Top, Pennsylvania. Before coming to Brown for graduate school, Aaron studied at Hamilton College and Dartmouth College, earning a B.A. in Chemistry and a B.E. in Chemical Engineering, respectively. Immediately after completing his undergraduate studies, Aaron worked at a Federally Funded Research and Development Center in the Washington, D.C. area for two years. During his employment, Aaron performed computational modeling in topics pertaining to chemical and biological weapon defense. Through these experiences Aaron developed an interest in chemical kinetics and catalysis, which ultimately led him to pursue graduate school at Brown. When not working on his graduate studies, Aaron plays defense for the Brown University Club Ice Hockey Team and collects action figures.

 
  • Eduardo Guzmán is a Los Angeles Native and a recent graduate from the University of Rhode Island. He received bachelor’s degrees in Chemical Engineering, French and Mathematics. Before joining the Goldsmith group in 2020, Eduardo worked at the Brookhaven National Laboratory (BNL) and the French National Centre for Scientific Research in Strasbourg (CNRS-Stras). At Brown, Eduardo hopes to meld his research training in catalysis with academic experience in Kinetics. The goal of his project is to study Polyfluorinated Substances (PFAS) using The Brown Shock Tube and other combustion methods. Outside of graduate school, Eduardo enjoys learning new languages, kayaking and engaging in political discourse online.
