+  interest in my research early on and for inviting me to come spend
+  some time at OCaml Labs in Cambridge, where I met Anil Madhavapeddy,
+  Stephen Dolan, and Leo White. I have learned so much from each of

+  Thanks to James McKinna for always asking intellectually
+  interesting, and at times challenging, questions. I have appreciate
+  our many conversations even though I spent days, weeks, sometimes

+  Speaking of offices, I also want to thank my peers from my own
