Leila
El Masri
Houston, Texas
BA: Chemistry + Political Science
Claremont McKenna College (2022)
Chemistry: Fall 2022
Atmospheric and Analytical Chemistry PhD student
Leila is interested in exploring the oxidation reactions of the environment through radical chemistry. She hopes to investigate the role of seaweed and other marine species' emissions via online chemical ionization mass spectrometry to elucidate their contribution to net global VOC emissions.

Christopher Frobenius
Orange County, CA
BS: Chemistry
UCSD (2022)
Chemistry: Winter 2023
Chemistry Master's student
Chris joined as a Lab Tech performing field work to investigate potential human health effects attributable to sea spray aerosols occurring in polluted environments. He is now a graduate student pursuing a M.S. in chemistry with a research project utilizing mass spectrometry under the guidance of Prof. Skip Pomeroy and Prof. Prather.

Justin Hamlin
Iowa City, Iowa
BA: Chemistry
University of Iowa (2017)
Chemistry: Fall 2022
Atmospheric & Analytical Chemistry PhD student
Following graduation, Justin served in the US Army as a Chemical Officer where he led a Chemical, Biological, Radiological, Nuclear, and Explosives (CBRNE) Response Team. He left the military in 2022 to pursue his PhD at UCSD where he studies biogenic volatile organic compounds and how they impact new particle formation in marine environments.

Jena Herbst
Corona, CA
BS: Ecology & Evolutionary Biology
University of California, Irvine (2022)
SIO: Fall 2023
Marine Chemistry PhD student
Jena was a CAICE SURP student in the Prather Lab in 2022 where she studied the chemical characterization of SOARS using TD-GCMS.

Maile Heyer
Oahu, Hawai'i
BS: Microbiology
UCSD (2022)
SIO: Fall 2022
Marine Biology PhD student
Maile's research broadly seeks to classify microbial communities and how they influence ecological systems. She will combine culture independent and dependent methods to simplify the dynamics within microbial communities so they can be manipulated and applied to today’s issues. This work will be completed under the guidance of the Prather and Zeigler labs at SIO.

Undergraduate Students
Senior Personnel and Postdocs
Chris Lee, PhD - Managing director
Chris is the Managing Director of NSF funded Center for Aerosol Impacts on Chemistry of the Environment (CAICE) and Balvi Filantropic Foundation funded Meta-Institute for Airborne Disease in a Changing Climate with interests in understanding the role of atmospheric aging and biological processes on the chemistry of sea spray aerosols. He joined the Prather Group in 2011 after graduating from the University of Wisconsin - Madison.
Email: leechris@ucsd.edu
Charbel received his Ph.D. in Civil and Environmental Engineering from Virginia Tech in 2022 and a B.E. in Mechanical Engineering from the Lebanese American University in 2018. He joined CAICE in 2022 as a postdoctoral scholar working under Prof. Kimberly A. Prather. Charbel's research aims to improve our understanding of the physical mechanisms of SSA generation and their role in the ejection of microbes and microplastics in the marine environment.
