Alan Sellinger Research Group

Principal Investigator


The Boss |

Alan Sellinger received his B.S. in Chemistry from Eastern Michigan University in 1989. After 2 years as a Research Associate at Gelman Sciences, Inc., he obtained his Ph.D. degree in 1997 from the University of Michigan in Macromolecular Science & Engineering under the guidance of Prof. Richard M. Laine. He then moved to Sandia National Laboratories in Albuquerque, NM for postdoctoral work with Prof. C. Jeffrey Brinker. From 1998 to 2003, he worked as a Research Scientist in the industrial R&D laboratories of Canon Research Center Americas, Palo Alto, CA and Opsys US Corporation, Fremont, CA. From 2003-2008, he held the position of Senior Scientist at the Institute of Materials Research and Engineering (IMRE), under the Agency for Science, Technology and Research (A*STAR), Republic of Singapore. He then moved to Stanford University from 2008-2012 as both Consulting Associate Professor in Materials Science & Engineering, and Executive Director of the Center for Advanced Molecular Photovoltaics (CAMP). Since 2012 he has been Professor of Chemistry/Materials Science at the Colorado School of Mines and Senior Scientist at the National Renewable Energy Lab (NREL). His research interests are in the synthesis of new hybrid materials for application in high surface materials for gas storage and catalyst supports, light emitting diodes (OLED), photovoltaics (OPV), thin film transistors (OTFT), and scintillation (radiation detection).

Graduate Students


Joshua Koubek

Joshua T. Koubek received his B.S. in chemistry (A.C.S. certified) specializing in forensic science with a minor in physics from The College of New Jersey in 2012.  After which, he was employed by BASF Corporation as an associate chemist assaying precious metals for two years.  He is currently a graduate student in Dr. Sellinger’s lab, where his research focuses on synthesizing and functionalizing carbon quantum dots for the use in photovoltaic and related applications.  His interests outside the lab include ballroom dancing, playing trombone, and enjoying the Colorado landscape.

Allison Lim

Allison graduated from Harvey Mudd College in 2016 with a B.S. in Chemistry with an emphasis in Materials (A.C.S. Certified). As a graduate student in Dr. Sellinger’s lab, she is currently focused on developing novel materials for plastic scintillators. Outside of lab, Allison enjoys playing soccer, hiking, and exploring Colorado.

Daniel Astridge

Daniel graduated from the University of Colorado, Boulder in 2018 with a B.A. in chemistry (ACS certified) with minors in math and biochemistry. As a graduate student in the Sellinger group, his research involves developing small molecules for use as dopants in plastic scintillators. In his spare time, Daniel loves all sports especially football (both American and the real kind), cooking, tropical fish keeping, and his two crazy labradoodles, Lucy and Dexter.

Caleb Chandler

Caleb completed a B.S. degree in Chemistry and B.A. degree in Computer science at Pacific Lutheran University in 2017. He then spent two years working at Los Alamos National Laboratory researching ceramic scintillators. As a current member of the Sellinger Group, Caleb is interested in studying plastic scintillators. Outside of lab he enjoys spending time with his wife and their dog, climbing, and hiking around Colorado.

Nicholas Walker |

After receiving his B.S. in Chemistry from California State University Bakersfield, Nicholas spent two years in industry developing silicone adhesives with applications in healthcare and electronics. He discovered a passion for analytical chemistry during this time and decided to transition into a full-time analytical role analyzing supplements and plant extracts for a laboratory Boulder. Nicholas is now an analytical chemist at Lightwave Logic, a small company that is developing an electro-optic modulator for the telecom and datacenter markets. His hobbies are hiking, skiing, gardening, and camping.
