Lesa enjoys hiking, camping and when the opportunity presents itself, scuba diving. “I could gaze at life underwater and explore the depths for hours on end, if my tank wouldn’t run out of air.” When she isn’t walking with her golden retriever, she finds herself in front of a computer screen deep in desktop publishing. “I have volunteered my ‘expertise’ to quite a few projects over the years and currently publish a monthly newsletter for my son’s school.”  Lesa began teaching at SU in spring 2005. “I love life science. It is challenging and rewarding to work with students as we learn about the intricacies of living things. Lesa is married with 2 children.
