Dr. Fernando Rosario-Ortiz

Version 3

Dr. Fernando Rosario graduated from the Environmental Science and Engineering Program from UCLA in 2006. He has a BS degree in Chemistry from the University of Puerto Rico, Rio Piedras. He joined the faculty at CU Boulder in 2008. Full CV is available here.


Garrett McKay


Garrett participated in the Environmental Engineering REU (research experience for undergraduates) program at CU in 2010 before joining the group as a PhD student during summer 2014. He graduated with a BA and MS in Chemistry from California State University Long Beach in 2013 and also worked as a part-time lecturer for one year, teaching general and organic chemistry. Garrett’s research is focused on DOM photochemistry.

Ariel Retuta


Ariel graduated with a BS in Environmental Engineering from CU Boulder. She was an undergraduate research assistant with the Rosario Group and officially joined as a Masters student in Spring 2016 focusing on DOC mobilization from thermally impacted soils in forested watersheds. Outside of her research work, Ariel enjoys climbing, hiking, running, and mountain biking!

Kylie Couch


Kylie graduated from California State University Long Beach in 2016 with a BS in Chemical Engineering and a BA in Chemistry. She joined the group in Fall 2016 to start working on a PhD in Environmental Engineering at CU Boulder. She is currently studying the photochemistry of DOM.

Yun (Rosa) Yu


Yun Yu got her PhD in Environmental and Water Resources Engineering at University of Massachusetts Amherst. Her primary research focus is drinking water quality and water chemistry, emphasizing the formation and degradation of regulated and unregulated disinfection byproducts (DBPs) in public water systems. She is especially interested in emerging nitrogenous DBPs, including haloacetonitriles, haloacetamides and N-chloro-haloacetamides, whose occurrence in drinking waters is of increasing health concern due to their substantial toxicological potencies. Through her research, she hopes to provide water managers and engineers with a more comprehensive understanding of the fate of these emerging contaminants in drinking waters from the source water to consumers’ tap and ultimately to help protect the public from the exposure to these hazardous DBPs.

She obtained her Ph.D. degree in Environmental Engineering from Gwangju Institute of Science and Technology (GIST) in South Korea in 2012. Her work focused on the study of the photochemistry of wastewater-derived organic matter and the characterization of organic carbon in aerosols.

Stephanie Kover


Stephanie Kover joined the group in the spring of 2012. She graduated from the University of Nevada, Reno in 2011 with a B.S. in Civil Engineering.  Stephanie’s research focused on the photochemical fate of compounds within COREXIT, the chemical dispersant applied as part of the response to the BP Deepwater Horizon oil spill in the Gulf of Mexico. Stephanie is co-advised by Prof. Karl Linden and graduated with a MS in the spring of 2013.


Caitlin Glover


Caitlin Glover joined the group in the summer of 2010.  She graduated from Wheaton College (MA) in 2009 with a Bachelors degree in Chemistry.  She received the NSF GRF in the spring of 2011 and successfully graduated in the spring of 2015. Caitlin is currently a post doc at SNWA.

Julie Korak


Julie joined the group in 2011. She graduated in 2009 from the University of Colorado-Boulder with B.S. degrees in Chemical and Environmental Engineering. She received her PhD in 2014.  She also received the NSF GRP in the Fall of 2010. She was a post doc researcher at the lab from 2014-2015. She is now employed at the US Bureau of Reclamation.

Simón Mostafa


Simón joined the group in the spring of 2012. He completed his B.S. and M.S. degrees in Environmental Engineering at the University of Central Florida. He was awarded an EPA graduate fellowship in the spring of 2012.Simon successfully defended his PhD in the spring of 2015.

Kaelin Cawley


Kaelin graduated with a BS in Natural Resources and MS in Environmental Science from The Ohio State University.  She completed her PhD in Environmental Engineering at the University of Colorado at Boulder.  While a postdoctoral fellow for the Everglades National Park at Florida International University (Miami, FL), she studied the photo- and bio-reactivity of dissolved organic matter (DOM).  Her research focuses on the photo-production of reactive oxygen species from natural and wastewater effluent derived DOM. She is now employed at NEON in Boulder, Colorado.
