Notes from the Head
 
 
 

Yes, we’re now in the second week of the second semester affected by the pandemic, and yes, we’re still in a socially-distant, meet-on-Zoom, twice-weekly saliva-testing world. (Side note: Who else besides me has found the funnels to be a game-changing innovation?) But unlike in Fall, there’s now tangible, local-area evidence of progress toward COVID-19 immunity.  Indeed, as of this morning, more than 28,000 vaccines have been administered in Champaign County, and 2.5% of the eligible population of the county has received both vaccines.

In our excitement to return to the activities–and people–we’ve sorely missed, I hope we’ll remember to pause and reflect on lessons learned during the past year. In particular, I hope we’ll ponder how our academic and professional endeavors should continue to evolve, and perhaps even be improved, in the future. Enhanced accessibility is something that comes to my mind: More than 200 attendees from more than 20 states and countries participated in MSCAR last October. Three weeks ago, approximately 50 of our alumni, friends, students and faculty gathered for a virtual reception during AMS Annual Meeting. And later this month, a virtual recruitment event will be held for prospective graduate students. In each of these examples, attendance was (or will be) possible only because the cost/travel/logistics barrier was removed. Of course, there’s still value for in-person activities, and still room for improvement of virtual ones, so let’s continue to innovate, ATMS! Have a great February.

-Jeff Trapp, Department Head
