# The Guys ## expand\_more **HGWISE**: Harvard Graduate Women in Science and Engineering ## Mark Baum ### HGWISE Guys Co-Chair #### PhD Student in the Earth and Planetary Sciences Program ##### Contact: ![Mark](/sites/g/files/omnuum3536/files/styles/hwp_1_1__360x360_scale/public/hgwise/files/personal-photo.jpg?itok=ft3oETCB) I'm a PhD student in the Department of Earth and Planetary Sciences working on the environmental history of Mars, mostly related to the interaction between large-scale hydrology and climate. I help plan events for the main organization and, together with Jack and Tim, started HGWISE Guys to get more guys involved with the group. ## Tim Clements ### HGWISE Guys Co-Chair #### PhD Student in the Earth and Planetary Sciences Program ##### Contact: ![TimClements](/sites/g/files/omnuum3536/files/styles/hwp_1_1__360x360_scale/public/hgwise/files/tim_hgwise.jpg?itok=D2dGn7xQ) I am third year graduate student in Earth and Planetary Sciences. My research focuses on monitoring groundwater with the ambient seismic wavefield. I grew up in Saratoga Springs, NY. I graduated from Cornell Engineering in 2015, where I studied geoscience and physics. Outside of work, I enjoy running, hiking, and browsing used book and record stores. ## Jack Hensley ### HGWISE Guys Co-Chair #### PhD Student in the Environmental Science and Engineering Program ##### Contact: ![Jack](/sites/g/files/omnuum3536/files/styles/hwp_1_1__360x360_scale/public/hgwise/files/img_0861.jpg?itok=mCITpIWS) Hey there! I’m a second year in Frank Keutsch’s lab, where I study atmospheric chemistry with new instruments. I grew up just north of San Francisco, then took a not so large leap to UC Berkeley for undergrad, followed by a much larger leap to ETH-Zurich, where I completed a master’s degree prior to coming to Harvard. Over the weekend, you could probably find me reading a book at Darwin’s or attempting to do something outdoorsy.
