The Program:
As the visits wind down, I'm finding myself almost hoping to get turned off by last few visits, just so I can keep my decision to a minimum number of options. Sadly (?), Cal Tech put on yet another great visit, and their program is another one of those move-with-the-times, flexibility-oriented setups that I've been looking for. Cal Tech doesn't have a TA requirement per se (although, because it's such a small school, pretty much everyone ends up TAing a low-level chemistry course their first year), and the course requirement is just "Five", with no specifications about which courses those might be. Chemistry students can work in any lab they want, and if you happen to want to change your degree's focus for some reason, the only roadblock seems to be a small amount of paperwork. In fact, Cal Tech prides itself on its relative lack of red tape, and it's able to pull that off thanks to a remarkably small program (900 undergrads and 1200 grad students total) and an unfairly high concentration of resources. Since Lawrence Berkeley Lab has been slow to finish its building, Cal Tech is the current epicenter of the Joint Center for Artificial Photosynthesis (JCAP), and the JCAP building on campus is basically the equivalent of the Broad for semi-conductors, but with half the number of people running around (if that). And even if solar panels aren't your bag, Cal Tech has core facilities out the wazoo, with no real time concern built in. Of course, when it comes to bigger crystallography projects, Cal Tech has to use its synchrotron beam-line up at Stanford, but by and large the school's reputation has allowed it to erase pretty much all the potential drawbacks of a small program. At this point in the interviews, you start noticing that every school has its curricular quirk, and Cal Tech's is a series of research proposals (or "props", as the abbreviation-obsessed student body has it), starting with two during the second-year qual season and ending with four during thesis time. As usual, Cal Tech is able to put a positive spin on this requirement, arguing that the extra thinking required for the props is the perfect lead-in to an academic career, where research proposals are the essence of your livelihood. This is not to say that Cal Tech explicitly pushes academia (and at least one faculty member I spoke to thought they should be pushing it more), but it does mean that Cal Tech does a very good job placing professors just about everywhere. Of course, the high level of research also doesn't hurt.
The Environment:
I was half expecting to dislike Cal Tech, and a lot of that expectation had to do with the location. My big turn-off at Scripps was the fact that it felt like a commuter school, and I figured that the same would be true of everywhere else in Southern California. Cal Tech, however, has a genuine community, and while size may have something to do with it, it's not really a fair argument, since the chemistry program there is the same size as Scripps's (Chemistry is the largest graduate program on campus by a mile, to the point where most other departments think of the chemists as a massive, globular clique). I think the housing situation may be one of the biggest factors: Cal Tech has a cabin-like cluster of graduate apartments called the Catalinas (or the "Cats", again with the abbreviations), which serve as a freshman-year-dorm surrogate for most of the first-years. After a year or two in the Cats, most students seem to disperse into Pasadena or beyond, but I think that first exposure to communal living, similar to UCSF, keeps the student body pretty well bonded. As for the car situation, LA differs from San Diego slightly in that most parts of the city have their own downtown area, and as long as you stay in your neighborhood, you'll likely be able to get around by bike or foot. Pasadena is definitely a town in that mold, and it feels more like Palo Alto than La Jolla, with the Gold Line serving as the Pasadena/LA equivalent to Cal Train for Palo Alto/San Francisco. The upshot is that about half the students at Cal Tech drive, and the others use bikes and public transportation to get where they need to be. As far as environment goes, Pasadena is a pretty gorgeous town. Cal Tech's campus feels very similar to Pomona, and Pasadena itself has more amenities (the Rose Bowl, the Huntington Gardens, a relatively legitimate downtown) than Claremont had to offer. The beaches and mountains are very accessible, with the closest hiking about a 10-minute drive away, and downtown LA has a good amount to offer, even if it has significantly more sprawl than San Francisco.
The Visit:
Cal Tech did a good job maximizing our chances for informal interaction with students. Our Thursday schedule was pretty much all aimed at getting us to talk to students, with a poster session, buffet dinner, and kegger in the Cats all scheduled in rapid succession. On Friday, every prospective had her own schedule, with coffee and snacks situated at random locations throughout campus with students manning the fort throughout the day. Of course, we had the obligatory Friday night dinner and party, and a Saturday fun day to top it off, so overall I had ample opportunity to interact with the current students and prospectives. There were 37 of us visiting campus, so it ended up feeling pretty similar to a lot of the chemistry programs I've seen thus far, especially since the usual suspects were once again out in force during this visit. The meetings themselves were once again communal, although the number of prospectives in attendance fluctuated pretty dramatically. Bob Grubbs apparently had a crew of about 20 people meet with him, and, since he doesn't have much interest in taking new students, he proceeded to spend the full half-hour looking at people's nametags and chatting with them about the schools they had attended. In any cases, my meetings were all very solid, with the one scheduling casualty being Dave Tirrell, whose students were nonetheless fun to chat with. Grubbs left for France Friday afternoon, so Theo Agapie (along with his dogs, wife, and child -- apparently Sarah Reisman carried her baby on a visitation hike a couple years ago and, not to be outdone, Theo's been bringing the whole crew every since) took a bunch of us hiking on Saturday up in the San Gabriel Mountains, while Tom Miller brought some people to the beach, Andre Hoelzer went to the Huntington Gardens, and Long Cai organized an impromptu Laser Tag outing (which he was, apparently, extremely jazzed about). Cal Tech, like a lot of the programs I've seen, did a lot of subgroup splitting, with each sub-discipline getting its own set of lab tours and having dinner at a different restaurant in Old Town Pasadena (the chemical biologists went to Il Fornaio with Linda Hsieh-Wilson and Andre Hoelzer for some nice Italian food). But there was a good amount of time to interact with the group at large, and there was enough free time during the visit day to keep it from getting too exhausting.
The Faculty:
I don't know why I found this surprising at first, but Cal Tech's chemistry department writ large has its hands in a good deal of biology. There are a bunch of stories of people like Dennis Dougherty (physical organic) and Jacqui Barton (electrochemistry) making a strong transition to chemical biology, and even physical chemists like Long Cai and Jim Heath are really interested in solving biological problems, and for me that means that there's a huge amount of exciting research happening there. Dougherty and Tirrell have some amazing techniques (both, interestingly enough, involving non-canonical amino acids) for probing proteins, and Jim Heath has one of the most impressive cancer treatment platforms I've seen anywhere on these visits. Cal Tech also has a token young professor doing exciting imaging research (Mikhail Shapiro), and I had a great interaction with him, although I'm going to need to talk to some of his lab members before I start falling head over heels. By and large, Cal Tech's faculty is pretty hands-off and has pretty high expectations, which means that life can and will be stressful, especially when you add in props, but the labs are typically fairly small and have an inordinate number of resources (Shapiro, for instance, has two MRIs of his own in addition to the two core facility scanners). And the younger faculty seem to be pretty awesome people: the most famous story concerns a group of prospectives signing a form saying they would come to Cal Tech if Sarah Reisman did a keg stand (which she did, although many of them didn't keep up their end of the bargain), but there's also other weird anecdotes floating around, like Theo Agapie eating somewhere between 22 and 24 cheeseburgers to win some contest and Tom Miller trying to get a bunch of prospectives to go surfing even though he has no surfing experience to speak of. Cal Tech actually seems like a pretty amazing place to be a young faculty member, since the school seems to invest pretty heavily in its associate faculty -- Hoeltz was extremely excited about the fact that he was able to design his own lab when he was hired (and it is pretty gorgeous). So while a lot of the older faculty are constantly on the move (Tirrell and Dervan were gone all weekend, and Barton, Heath, and Grubbs at least all flew out on Friday), the ones who were around were all fun to interact with. The community feel isn't quite what it was at Columbia, but it definitely does feel like a good group.
The Students:
The Cal Tech undergraduate community is decidedly and famously weird, but the grad students can all say, at the least, that they didn't go to Cal Tech for undergrad. To be sure, there's definitely a good amount of social awkwardness present in the chemistry department's ranks, but by and large Cal Tech seems to have a very solid community of good people. There's a measured amount of lab cliquiness, fueled largely by Dennis Dougherty's group (which, to be fair, has some pretty awesome people), but overall the chemists at Cal Tech seem to do a pretty good job hanging out with each other. Again, I think part of this has to do with the Cats set-up, which would have turned me off a few years ago, but now seems nostalgically cheesy. The major social drawback of Cal Tech is that it's just a whole bunch of scientists, but it seems like the students who need a more well-rounded social life are able to find ways to get it in Pasadena. As far as the research goes, Cal Tech's students have the same "my life sucks, but I'm glad it sucks here" mentality that seems to permeate a lot of the top-tier schools I've seen. Everyone I talked to was pretty honest about the ups and downs of their experiences there, but no one seemed unhappy, although some had needed to switch labs, and Cal Tech, like Harvard, went through a rash of suicides a few years back, so there's definitely a history of unrest. That being said, Cal Tech, like Harvard, realized at a certain point that they needed to start making their students' lives less miserable, so there's now a summer softball league, weekly happy hours for each department, and a sizable number of clubs -- with more student involvement than I've seen anywhere else. The students I spoke to also talked up the comparative size of the program, saying that, while there were as many great students at Cal Tech as at Berkeley or Harvard, the concentration was significantly higher, meaning that the intellectual atmosphere was overwhelmingly invigorating. It also bears mentioning that I spoke to several female students who had chosen Cal Tech because it had many more female role models and a much more enlightened atmosphere than a place like Scripps or Harvard.
The Cohort:
The Cal Tech visit felt pretty similar to Columbia's in that many of the conversations I had were about how surprisingly great the visit had been. The size may end up being a drawback for some in the final decision, but by the end of the weekend, pretty much everyone I spoke to still had Cal Tech on their list. I met some new people on this weekend, all of whom were pretty cool, although again, there's really no telling at this point where anyone will end up. There's also the added complication that, at this point in the process, the actual decision date is starting to loom, so the concentration of "where, where, where?" conversations was on the high side. But we had the chance to let loose a little during the visit -- there was a beer pong table on Thursday night, and there were pool tables on Friday. They kept us busy enough that I didn't have a chance to go night-swimming at the hotel (the Pasadena Westin, which was pretty snazzy), but I didn't mind too much. My roommate at the hotel had actually applied to the Biophysics program, but for some reason he was accepted to chemistry. It seemed like he had a pretty good visit with the physical chemists anyway, but I didn't get a chance to ask him explicitly. This also marks the fourth time a random Pomona student has shown up to a visit, which was once again a nice surprise.
The Impression:
Cal Tech passed the gut test, which is pretty exciting, since only Harvard, Columbia, and a couple labs at Berkeley and Cal Tech gave me the same feeling of homeyness. The major drawback here is that the onus would really be on me to make sure that I maintain a healthy social life outside of school, but even if LA is more impersonal than San Francisco or Boston, I at least have the benefit of a fairly robust past life in the city. Pasadena would also give me pretty much all the benefits of the Bay Area -- lots of great outdoorsy stuff nearby, a decent connection to the city, and a fairly vibrant local downtown. As far as the program goes, I don't think I realized how important it is for me to have a smaller community on campus -- I guess it's just the liberal arts background seeping through. But Cal Tech has all of the small school feel that I love without any of the resource hangups that concerned me at Columbia. My only programmatic concern is the lack of official rotations, and while the program is certainly flexible enough to allow informal rotations (especially if I show up early), I really liked the places that have rotations as a cultural component of the grad school experience. But at the end of the day, I don't think rotations are going to be the thing that keeps me from Cal Tech. At this point, it's a matter of making sure the labs I like the most there are really all they seem to be, and that means more conversations with students. However it ends up, I know Cal Tech will be in the conversation.
