Hi! I am Haipeng "Jimmie" Lin (林海芃), a PhD student at the Atmospheric Chemistry Modeling Group, Harvard University. My research focuses on development and evaluation of atmospheric chemistry models such as the GEOS-Chem chemical transport model. Read more about my research in its dedicated page.

I formerly led the development of the WRF-GC coupled meteorology-chemistry model. I still participate in its development through code maintenance, coordinating with the GEOS-Chem team, and answering support requests for WRF-GC.

Please feel free to reach out to me at hplin at seas.harvard.edu.

Personal Life

I grew up in the wonderful weather of Lisbon, Portugal and later returned to Beijing, China at age 12. I have always been fond of writing code, tracing my roots to modding forum software for a Pokémon community board. I have earned my B.Sc. in Physics at Peking University (PKU), and proudly studied at High School Affiliated to Renmin University of China (RDFZ) before that.

During my final year at Peking University I led the PKU Helper student-developed social app for PKU students, providing mobile services such as classroom and grades info and an anonymous social platform. Before leading the team, I was a backend programmer.

Programming

I was born in PHP, raised in Ruby, love Haskell, and write Fortran for a living. I also occasionally write Julia, Makefiles, Python, and I regex my way out of problems more often than I admit.

(Human) Languages

I speak Portuguese, Mandarin and English.

Travel

I had the privilege to growing up in a family who for various reasons had the perk of moving around the world quite a bit. I have thus grown fond of going to many places in the world.

I lived for years in Lisbon, Beijing, currently live in Cambridge, MA and have formerly spent quite a few months in Brasilia.
