The New York CITTI Research Group
Welcome to the New York Climate Investigations: Theory To Impacts, a.k.a. New York CITTI, research group. We seek end-to-end understanding of climate processes, meaning from fundamental analytical theory to quantifying their real-world impacts. We have two main research strands:
- Monsoon rainfall. What controls when, where, and how intensely it rains within Earth's monsoon systems?
- Weather and climate impacts on New York City.
Group members
Spencer Hill (Assistant Professor, CCNY EAS)
My biggest passions are my wonderful family (wife, daughter, dog), science, and music. I deeply love my adopted hometown of NYC. My favorite pizza in the city (and therefore the world) is Lucali for whole pie and Bleecker Street Pizza for slices. My favorite bagels in the city (and therefore the world) are Absolute Bagel for a bagel w/ cream cheese and the original Russ & Daughters for a lox sandwich.
Alex Parsells (Ph.D. student, Columbia University DEES, group member since September 2022)
Alex is a second-year Ph.D. student at Columbia University studying the relationship between tropical rainfall and poleward energy transport. He has a background in astrophysics and enjoys backpacking, trivia, and White Castle.
Greg Randazzo (M.S. student, CCNY EAS, group member since August 2023)
Inspired by the 2023 Northeast wildfire season, I am currently working to understand the influence of large scale synoptic features on the trajectory of wildfire smoke plumes. In my free time I love learning foreign languages and taking care of my plants. https://dynamicplanet.net/
Haochang Luo (Postdoc, CCNY EAS, group member since April 2024)
Haochang graduated from the University of Michigan with a PhD in Climate and Space Sciences and Engineering. Most of his research focuses on tropical dynamics. His research interests include convection, precipitation, tropical meteorology, climate change, and multi-scale interactions.
Edda Monique Hobuss (B.S. student, CCNY, group member since August 2024)
Edda began her academic journey in linguistics but transitioned to physics. Although she has researched light-matter interaction in 2D materials, she is excited about understanding the dynamic interactions of Earth's atmosphere. In her free time, Edda enjoys spending time with her husband, reading, and running, and visiting Gantry State Park for the Manhattan views and the chicken and waffles from Sweet Chick.
Michelle Wagner (M.S. student, CCNY EAS, group member since September 2024)
Michelle graduated from CCNY with a degree in Earth Systems Science. Her research background includes satellite-based imaging applications for environmental monitoring, characterization of phytoplankton bloom dynamics and algorithm optimization for remote sensing data products that aid in HAB detection. Through her EAS master's program, she is exploring atmospheric and climate dynamics. She likes to sing and play music in her free time.
Shreya Keshri (Postdoc, CCNY EAS, group member since February 2025)
Shreya Keshri (Postdoc, CCNY EAS, group member since February 2025) I completed my Ph.D. in Atmospheric Science from IISER Pune, India. My research focuses on the role of tropical-extratropical interactions in the genesis and variability of synoptic-scale tropical motions and how they respond to climate change. I am broadly interested in tropical meteorology, equatorial waves and large-scale atmospheric dynamics. In my free time I like to cook, read, go for a walk and spend time with my family.
