I was out for an evening run on the Lehigh University cross country fields. Three miles in, my calves were burning and I felt like it was turning into a bad run. I had a stressful day and had not slept well last night, and was considering cutting my losses and ending early. Then I […]
Congratulations to Chelsey Shepsko and Hang Dong for earning their Ph.D.’s in 2019! Chelsey Shepsko Dissertation: “Advancement of the Hybrid Ion Exchange Nitrogen and Phosphate (HIX-NP) Recovery from Waste Water and a New Approach to Brine-Free Nitrate Removal” Hang Dong Dissertation: “Hybrid Ion Exchange Process Driven by Carbon Dioxide”
Cold, rainy, hilly, amazing, depleting, exhilarating. These are some simple words to describe my first marathon. When I told my non-running friends that I signed up for the Pittsburgh marathon, most looked at me and subtly shook their heads. Some said I was crazy, others said my knees would wear down from all the running. […]
