Taken Nov. 2016 in front of the Dept. of Atmospheric Science.

Prof. Michael M. Bell

Michael Bell received his B.A. in Religion from the University of Florida in 1996, and his B.S. in Applied Mathematics with a minor in Meteorology at Metropolitan State College of Denver in 2001. He completed his M.S. in 2006 from the Department of Atmospheric Science at Colorado State University and Ph.D. in Meteorology in 2010 from the Naval Postgraduate School. Michael was an Assistant Professor at the University of Hawaii at Manoa from 2012 to 2016 prior to joining the CSU ATS faculty as an Associate Professor in 2016.


Annette Foerster (Post-doctoral Researcher)

Annette received her M.S. in Physics from Karlsruhe Institute of Technology, Germany in 2011 and started her Ph. D. studies in Hawaiʻi in Fall 2012. Her fields of interest are remote sensing, mesoscale and tropical meteorology, with a focus on radar meteorology and tropical cyclones. Her current research aims to study the thermodynamic structure of the inner core region of tropical cyclones using airborne radar data.

Phil Klotzbach (Research Scientist III)

Phil Klotzbach is a Research Scientist in the Department of Atmospheric Science at Colorado State University. He received his Ph.D. in Atmospheric Science from CSU in 2007. Klotzbach has been employed in the Department of Atmospheric Science for the past fifteen years where he has been co-author on the Atlantic basin hurricane forecasts with Dr. William Gray. He became first author on the seasonal hurricane forecasts in 2006. Klotzbach developed the two-week forecasts currently being issued during the peak months of the hurricane season between August-October. He developed the Landfalling Hurricane Probability Webpage (available online at in partnership with the GeoGraphics Laboratory at Bridgewater State University. This webpage provides hurricane landfall probabilities for the entire United States coastline from Brownsville, Texas to Eastport, Maine as well as the Caribbean. He has published over two dozen articles in peer-reviewed journals such as Journal of Climate, Weather and Forecasting, and Geophysical Research Letters.

Klotzbach graduated from Bridgewater State College with a BS degree in Geography in 1999. He then attended Colorado State University where he received his Masters degree in Atmospheric Science in 2002. After receiving his Masters degree in 2002, Klotzbach thru-hiked the Appalachian Trail from Georgia to Maine (2100+ miles). He has also climbed all 54 14,000 foot peaks in Colorado, and has completed eight marathons and five ultra-marathons.

Current Students

Eleanor Delap (MS)

Ellie is a master's candidate studying the tropical cylone boundary layer. She received her B.S. in Meteorology from Valparaiso in 2015.

Jonathan Martinez (PhD)

Jon was born and raised in Hollywood, Florida. Experiencing several hurricanes during his 21 years of living in South Florida sparked his interest in research with tropical cyclones. Jon moved to Tallahassee, Florida in 2012 to attend the Florida State University where he earned a B.S. in Meteorology in 2014. He spent the summer of 2013 and 2014 in Boulder, Colorado at the National Center for Atmospheric Research (NCAR) doing research as a Significant Opportunities in Atmospheric Research and Science (SOARS) protege. Jonʻs M.S. research investigated the kinematic and thermodynamic radial structure of tropical cyclones using aircraft flight level data. His Ph.D research is focusing on understanding the impacts of convective processes on tropical cyclone intensification using radar analyses. During his free time, Jon enjoys hiking and exercising.

Muhammed Naufal Razin (MS)

Naufal is a master's candidate studying the role of stratiform convection in tropical cyclone intensity change. He received his B.S. in Meteorology from the University of Hawaii in 2015.

Ting-Yu Cha (MS)

Ting-Yu is a master's candidate studying radar applications as part of the LROSE project. She received her B.S. in Meteorology from National Taiwan University in 2016.

Ben Trabing (MS)

Ben is a master's candidate studying multi-scale interactions involved in tropical cyclone intensity change. He received his B.S. in Meteorology from the University of Oklahoma in 2016.
