Jessica Tryner

I started working on my PhD in mechanical engineering at CSU in the fall of 2011 as a participant in the Multidisciplinary Approaches to Sustainable Bioenergy IGERT program. Before moving to Colorado, I had spent most of my life living in New Jersey, where I attended Rowan University and completed my B.S. in mechanical engineering. I came to CSU to pursue research related to the use of traditional biomass fuels in the developing world. I am interested in finding ways to improve the way these fuels are currently utilized to increase environmental sustainability and reduce negative health effects. I hope that through the multidisciplinary component of my research, I can also seek greater understanding of how these goals can be accomplished in ways that encourage more equitable social and economic development. Besides hanging out at the EECL, my hobbies include hiking, snowboarding, photography, and sewing.
Christian L'Orange

I have been working at the EECL since the fall of 2006 and completed my M.S. in mechanical engineering in the summer of 2009. I have now been given the opportunity to continue my research and work towards my PhD. My time at the lab has been devoted towards the clean cook stoves project. My research seeks to characterize and understand the toxic emissions released from biomass cook stoves from around the world and the implications of those emissions on the environment and human health. When not working or in class I can usually be found in the mountains surrounding Fort Collins.
Andrew Hockett

I grew up outside of Seattle. I began my undergraduate education as a physics major at Willamette University in Salem Oregon. Upon realizing I wanted to be an engineer, I transferred to the University of Southern California through a 3-2 dual degree program, where I earned a B.S. in mechanical engineering. Afterwards, I spent two years in Los Angeles working in manufacturing. Now I am pursuing a Ph.D. in mechanical engineering while working as a research assistant. My research project involves a new combustion mode known as RCCI, which blends both gasoline and diesel fuels in a compression ignition engine. The aim of this technology is to achieve high fuel efficiency while exceeding emissions regulations. My research interests include fundamental combustion, chemically reacting flows, efficiency of engines and power plants, pollution formation, carbon capture, and general thermal and fluid sciences.
Tim Vaughn

My research began in New Jersey at Rowan University where I worked under Dr. Marchese studying the ignition delay of biodiesel and biodiesel surrogate fuels. I have since transplanted to Colorado to work on my PhD at CSU and the EECL. Currently, I am learning to model the combustion of methyl esters using Chemkin, and in the future will perform homogeneous charge pre-mixed compression ignition experiments using the Rapid Compression Machine and fast NOx analyzer. I also assist in developing a droplet ignition apparatus which will use Planar Laser-Fluorescence and Laser Induced-Incandescence to measure pollutant formation of FAME fuel droplets. In my “spare time” I enjoy the outdoors, snowboarding, playing the drums, and swinging wrenches at my car.
Arunachalam Lakshminarayanan

I started working on my MS at the Colorado State University and EECL in August 2010, focusing on Straight Vegetable Oils as alternative fuels for engine applications. I received my B.S. in Mechanical Engineering from University of Pune, India in May 2007. Since then I had been working for an engine manufacturing company in Mumbai as a core member in techno-commercial area. I will be working under Dr. Daniel Olsen from Mechanical Engineering and Dr. Catherine Keske from Agricultural Economics to develop sustainable Vegetable Oil and bio-diesel as fuels while meeting the current emission norms. In my spare time, I enjoy photography, reading and writing.
Marc Baumgardner

I received my undergraduate degree Chemical Engineering from Georgia Tech back in 2005. For the next five years, I worked for UOP, a company that designs and licenses technology, primarily, for the refining and petrochemical industries. While with UOP I got the opportunity to work in and with many different refineries across the world. I also gained some really great insight on the current and future state of the refining industry. It was also during this time that I started to gain an increasing interest in discovering what alternatives there might be to petroleum-based fuels. I decided to come here to Colorado State because of the Universitys over-arching focus and goal of not only advancing the knowledge of bioenergy, but also of making immediate impacts in society for the better - no better place is this exemplified than here at the EECL. While here at CSU I will be pursuing my PhD in Mechanical Engineering with a focus on investigating the modeling and use of alternative fuels in various modes of internal combustion engines.
Clay Bell

Originally from West Virginia, I have a life long love for the outdoors and particularly snowsports. I earned my BS and MS in Mechanical Engineering at West Virginia University, where I worked with the Center for Alternative Fuels, Engines and Emissions (CAFEE). As a PhD candidate in Mechanical Engineering at Colorado State University I've had many great opportunities since I began in August 2011. Working with Dan Zimmerle at the EECL, I've had the chance to work closely with several small technology companies on a variety of projects ranging from the evaluation of equipment for compressed air energy storage systems, to modeling and simulation of thermo-mechanical systems, as well as the evaluation of geothermal potential at active oil and gas wells. I'm also the 2012-2013 Mechanical Engineering PhD Teaching Fellow, which provides the opportunity to teach MECH 237: Introduction to Thermal Sciences. I have really enjoyed my time in Fort Collins as both an instructor and a researcher at CSU and look forward to spending a couple more years here to finish my degree.
