One of the pleasures of teaching is seeing how well your former students are doing in their new adventures. I ran into JHU ME alumni Bailey Hannon and Martha Whiting, BS 2015 at ARVO. I taught them both in Biosolids and Martha built an essential test fixture for my lab as an REU student. Both were presenting their research and Bailey gave a great talk on using machine learning to automatically count axons. Bailey is a 4th year PhD student in BME at Georgia Tech and Martha is a 3rd year MD student at U. of Maryland.
