Achievements and announcements

DRIVE: Doctoral Research Innovation, Vision, and Excellence

Tara McKinnon collecting aquatic insects using a Suber samplerStarting in January 2021, the Nevada DRIVE program promotes recruitment and retention of Ph.D. students at the University. GPHS was successful in obtaining 3 semesters of DRIVE funds around the theme of “Nevada Water” and in support of first-generation college students and Ph.D. students from historically underrepresented groups. Ms. Tara McKinnon is our first DRIVE scholar (Fall 2021). Tara's research focuses on understanding the ways that irrigation withdrawals from streams in the Shasta region affect the aquatic ecology of these streams. Because both aquatic and terrestrial insects are key food sources in these riparian ecosystems, her project has a strong focus on insect sampling. While on DRIVE funding, Tara gained expertise in terrestrial insect identification and processed hundreds of insect samples. She also trained and mentored local volunteers, who clocked over 600 hours assisting with these insect samples. 

In fall 2022, GPHS will be using our DRIVE funding for recruiting one to two Ph.D. students. We thank University President Brian Sandoval; Vice President for Research and Innovation, Mridul Gautam; and Executive Vice President & Provost, Jeff Thompson, for making the DRIVE program possible.

Krishna Pagilla's wastewater survey tracks COVID-19 Delta variant in Truckee Meadows

Student testing samplesThe highly contagious COVID-19 Delta variant has been successfully identified and tracked in Truckee Meadows wastewater since June 2021, establishing the monitoring process as a viable means of detecting new COVID-19 variants that may be present in Washoe County.

And while the Truckee Meadows COVID risk meter – based on several factors – remains very high, the level of Delta variant in the community has been trending down since September and the Risk Meter prediction is for the risk in the community to inch lower next week.

In continuing studies and monitoring of Truckee Meadows wastewater, researchers at the University of Nevada, Reno, working with the City of Sparks, the City of Reno and Washoe County, have been able to identify a number of COVID-19 variants that are present in the community, and initially detected the variants in wastewater months before they were identified from clinical monitoring. can detect them in wastewater simultaneously or even before being detected through sequencing of clinical samples.
