I first discovered the beauty and elegance of phages during my Ph.D. studies, which were focused on the DNA packaging enzyme of E. coli phage lambda. During my post-doctoral work at MIT, I switched to the field of protein structure and folding. I continued this work in my own lab investigating the thermodynamics and kinetics of folding of the SH3 domain. I have also worked extensively on the functioning of SH3 domains in budding yeast. Luckily, as time went on in my own lab, I was able to move back into the phage field.
