Hi! I'm Jeffrey Mei, a PhD student at the MIT/WHOI Joint Program in Applied Ocean Science & Engineering.

My research interests are in data science and statistical modelling, in particular as applied to developing algorithms to accurately quantify sea ice thickness.

Research

My current research with my research supervisor, Dr. Ted Maksym (WHOI) lies in quantifying snow distribution and sea ice thicknesses, primarily in the Ross Sea. This is a two-pronged approach involving modeling ridge formation using discrete element models, and modeling snow distribution along ridges using statistical models and ice/snow data from cruises and ICE-Sat. I have recently participated in the PIPERS expedition to the Ross Sea to collect snow depth and ice thickness data. In the past, I have worked on localizing glacial calving by using local seismic arrays. To this end, I have accompanied Prof. David Holland (NYU) to Sermilik Fjord, Greenland to collect oceanographic and seismic data near Helheim Glacier.

I am also interested in statistical models and machine learning and have been using convolutional neural networks and computer vision techniques to identify pressure ridges in elevation data from IceBridge.

About Me

Deploying moorings in Sermilik Fjord, Greenland in August 2014.

Taking sea ice thickness measurements in the Ross Sea during PIPERS 2017.

I was born in Taiwan and moved to New Zealand at age 3. I went to Westlake Boys High School in Auckland, New Zealand, where I completed Cambridge International Examinations A levels in Mathematics, Physics, Chemistry and German Literature and also sat New Zealand Qualifications Authority Scholarship exams, receiving Scholarships in English, Art History, Chemistry and Mathematics with Calculus, and an Outstanding Scholarship in Statistics and Modelling.

For my undergraduate education, I was offered a full scholarship to New York University Abu Dhabi, a small liberal arts college in the Abu Dhabi, United Arab Emirates, where I graduated with a Bachelor of Science cum laude with a double major in Mathematics and Physics. I also spent two semesters studying abroad, one at each of NYU Berlin/Humboldt Universität zu Berlin and NYU Washington Square. I have done summer research with Dr. Ingyin Zaw at the Center for Cosmology and Particle Physics at NYU, Dr. David Hogg at the Max-Planck Institut für Astronomie in Heidelberg, Dr. Andy Haas at the Center for Cosmology and Particle Physics at NYU and Dr. David Holland at the Courant Institute of Mathematical Sciences at NYU.

I am now at the MIT/WHOI Joint Program in Applied Ocean Science & Engineering working under Dr. Ted Maksym (WHOI) as a PhD student. My research interests are in applying data science techniques to ocean science, developing discrete element models of pressure ridging in sea ice, and investigating the distribution of snow along pressure ridges.

In my spare time, I serve as the Treasurer for the MIT Badminton Club and as President of the Kiwis@MIT student group.
