Faculty promotions at Purdue approved by board

Purdue University's Board of Trustees on Friday (April 9) approved faculty promotions. The promotions are effective with the 2021-22 academic year and include Purdue EAPS professors Daniel R. Chavas, Marty D. Frisbee, Lisa R. Welp, and Gregory M. Michalski.

“Simple question” leads to multi-year research study about effects of alpine glacial meltwater on groundwater in mountainous regions

Alpine glaciers are formed high in the mountains and produce meltwaters that flow down the mountain. These meltwaters sustain life in mountain streams, lakes, and rivers. The meltwater from iconic frozen mountaintops is an essential building block to the Earth’s ecosystem, so when Jordyn Miller, PhD Candidate for Purdue Earth, Atmospheric, and Planetary Sciences (EAPS) asked her advisor a “simple” question years ago, she assumed there would be an answer readily available. She asked Dr. Marty Frisbee, EAPS hydrogeology professor, does meltwater from alpine glaciers contribute to mountain-block recharge and deep circulation within a mountain block. As it turns out, the simple question turned into a quest to deliver an answer because there is very little research in this area. In March of 2021, Miller published the first results of a multi-year research project.

Professor Mike Sori discusses his latest research about Triton, one of the moons of Neptune

Dr. Mike Sori, Professor of Planetary Geophysics, speaks about his recent publication in AGU titled, "Can Triton's Internal Heat Be Inferred From Its Ice Cap?" He discusses Triton (a moon of Neptune), its nitrogen ice cap, the “ocean world" moon's youthful surface, and the need for future spacecraft to further explore this part of our solar system.

Mars scientist examining the landscape through rover camera she helped design for NASA Perseverance mission

Briony Horgan raised her arms in triumph as the Mars rover Perseverance landed on Feb. 18, a symbolic declaration of mission success. That electric moment was just the beginning for the Purdue University scientist. With Perseverance on the ground and moving, Horgan is now focused on analyzing data from the instrument she works with: Mastcam-Z.

Atmospheric professors awarded grant for flexible, portable kit-based lab instruction

A group of atmospheric professors have recently been awarded a 2020-2021 Instructional Equipment Grant from the Office of the Provost for their proposal entitled “Flexible, Portable Kit-Based Laboratory instruction in Atmospheric Science.” This grant funding will be used to create lab kits that students can check out and use remotely.
