Dear Mrs. Lafferty (Vivian),
I was indeed sad to her the sad news about Dr. Lafferty. My heartfelt condolences to you and your family.
I was the second PhD student in Biomedical engineering program and had the honor and pleasure of speaking with Dr.Lafferty on many afternoons both about engineering and life in general over a period of 5 years. I used to look forward to the yearly barbecue in your backyard in Lexington where I would get the opportunity to spend the afternoon with Dr. Lafferty and assist him in barbecuing.
I am sorry that I did not have an opportunity to see him after my graduation.
My thoughts and prayers are with you and the family.
