Dr. Yalin joined the Department of Mechanical Engineering at Colorado State University (CSU) in 2002 and is currently a Full Professor. He received his undergraduate degree in Engineering Physics from Queen’s University in 1995, and Masters and PhD degrees from the Department of Mechanical and Aerospace Engineering at Princeton University in 1997 and 2000 respectively. From 2000 to 2002, he held a post-doctoral position at Stanford University in the Departments of Mechanical Engineering and Chemistry. His current research focuses on laser-based diagnostics and non-intrusive measurements of gases and plasmas. The diagnostics are used for studies of atmospheric plasmas, low-pressure plasmas, and plasma sputtering, with application towards plasma science, plasma-processing, and electric propulsion. Other interests include applications of lasers and plasmas to combustion, especially laser ignition of engines, and laser sensing for atmospheric science. Dr. Yalin has more than 40 journal publications, 70 conference proceedings and presentations, and 4 patents in these research areas. His awards include George T. Abell Outstanding Teaching & Service Faculty Award (2012) from CSU’s College of Engineering, Oliver R. Pennock Service Award (2011) from CSU, Ralph R. Teetor Educational Award (Aerospace area – 2009) from SAE, and the Abell Outstanding Early-Career Faculty Award (2007) from CSU’s College of Engineering. He also serves as Director of CSU’s NASA Space Grant Program. From 2002-2008 he served as the Vice-Chair and then Chair of the Applied Spectroscopy and Environmental Sensing Technical Group of the Optical Society of America. He is an Associate Fellow of the AIAA and currently serves as secretary of the AIAA Plasmadynamics and Laser (PD&L) Technical Committee.

Graduate Students

James Sipich, M.S. Student – Mechanical Engineering

Email: jsipich100@gmail.com
Office: Powerhouse Energy Institute

James joined the CLSD in the Fall of 2018 for his final year of undergraduate study. His research, under the advisement of Dr. Yalin and Dr. John Volckens, is focused on the applications of Laser-Induced Breakdown Spectroscopy (LIBS) to the characterization of inhalable aerosol particles. After receiving a Bachelor’s degree in Mechanical Engineering in May 2019, James will continue this research in the M.S. program at Colorado State University.

Tad Wegner, M.S. Student – Mechanical Engineering

Email: tad.wegner@colostate.edu
Office: Powerhouse Energy Institute

Tad joined CLSD in August of 2018 as a Master’s student in Mechanical Engineering. He received B.S. degrees in Engineering Physics and Nuclear, Plasma, and Radiological Engineering (NPRE) from the University of Illinois at Urbana-Champaign in May of 2018. As an undergraduate, he worked at the Center for Plasma-Material Interactions helping graduate students with their semiconductor manufacturing plasma research projects. Currently, Tad is working on using Two-Photon Absorption Laser Induced Fluorescence (TALIF) to measure the density of neutral xenon in electrostatic thruster plumes.

Undergraduate Students

AJ Puga, B.S. Student – Mechanical Engineering

Email: ajpuga@rams.colostate.edu
Office: Powerhouse Energy Institute

AJ joined the CLSD in the Spring of 2019. He currently is working closely with Ben Martinez on the open path cavity ring-down spectroscopy sensor measuring methane. His research will use this technique for measurement of other species within the atmosphere. He will receive his bachelor’s degree in Mechanical Engineering in May 2020.

Blake Duff, B.S. Student – Mechanical Engineering

Email: blaked34@rams.colostate.edu
Office: Powerhouse Energy Institute

Blake Duff joined the Center for Laser Sensing and Diagnostics as a research assistant in Spring 2019. He is in his final year as an undergraduate in mechanical engineering, and is conducting studies in laser-induced high energy plasma characterization for pulse power systems. Currently, his characterization studies regard optical emission spectroscopy (OES) of plasma channel formation using high power pulsed lasers.
