On Science Talks and the End of my Tour


Thinking back to my time as a postdoc in Hawaii, I can remember waiting around for invitations to give science talks at other institutions. My thesis work had fully matured, was yielding exciting results, and was promising to lead to even more exciting research directions. On top of that, I was following the advice I had received by branching out into other projects of my own design. I was eager to go out and share my science with other astronomers.

Unfortunately, the phone rang very infrequently. I gave talks at JPL here in Pasadena, and another at the University of Washington. Both were excellent experiences and confirmed my feelings that I was ready for other big stages. I later recognized that I should have been inviting myself to various places, but at the time I was feeling discouraged that I wasn't able to book good gigs, so to speak. After all, how was I going to get recognized as a good faculty candidate? How was I going to move to the next stage if I couldn't show off what I was doing?

Well, all that changed after I got the job I was seeking. Once I became an assistant professor, the phone finally started ringing. At first I thought this was rather ironic: now that I have the job I was hoping to advertise for, I finally get the chance to advertise. But it turns out things were working as they were supposed to. As an assistant prof. I was seen as a fully vetted speaker, someone definitely worthy of inviting to other institutions. And by taking these invitations, my efforts are certainly not wasted. I have tenure to earn, and as such I'm pretty much still applying for this job. And while a few usual suspects will write me letters of recommendation, my tenure committee will solicit many more letters from colleagues at other institutions. My advertising has just begun!

A big part of professional science is communication. I spend a large fraction of my time writing papers, writing proposals, writing letters of recommendation, giving lectures and giving talks. The small fraction of the time left over is spent writing code, planning observations and actually observing, in decreasing order of time spent. As such, a large part of my future (and ongoing) job evaluation is based on my ability to not only do good science, but communicate it clearly and enthusiastically to a broad scientific, and in some cases public audience.

Hitting the "talk circuit" in astronomy is a lot like a band playing gigs. As a new, struggling act (grad student) you first start locally giving talks at your group meeting. From there you give a journal club talk, whereby you give a 30-minute presentation about a research paper you read that week. Later, you might get invited to a neighboring institution to give a lunch talk. These are informal brown-bag affairs during which the speaker gives a 30-45 minute talk on their research project, while the audience of students, postdocs and a stray prof or two much on sandwiches. From there you give your thesis defense, and perhaps a postdoc job talk or two, and in astronomy it all culminates in a 15-minute dissertation talk at the American Astronomical Society meeting.

I vividly remember my dissertation talk. At first I was extremely disappointed that it was scheduled for the last session on the last day of the Austin meeting in Jan 2008. However, since there was nothing else for everyone left at the meeting to do, I had an audience of about 500 astronomers and I gave my presentation in the huge plenary session room, the stage flanked by two 40-foot projection screens. It was awesome!

After you graduate and take a postdoctoral position, you either wait around for the phone to ring like I did, or you do the smart thing and invite yourself to institutions. This is where the connections and friendships you built in grad school start to pay off. Give your buddy at Princeton a call and ask if you can get a Wednesday lunch-time seminar talk (a Wunch Talk as they call them). Book an early flight home for Christmas and stop over somewhere on the way to give the last theory seminar talk of the semester.

All of this presenting can be for naught, or even a net-negative, if you don't put the necessary time and preparation into your science talk. This is where paying close attention to the fine details of colloquium talks pays off. Take notes on what works and doesn't work in weekly talks at your institute. Talk to other postdocs and professors and get advice on how to make clear slides, tips on organization, and pointers on how to dress, where to look (e.g. not at the screen), how to handle Q&A, etc. As I tell my students, you spend months writing a paper and a dozen people in your subfield will read it carefully. But if you give a good talk, you can reach dozens at a time from a wide variety of subfields. You should therefore but as much or more effort into your talks.

The next step up involves giving colloquia. While lunch talks are like playing local bars or doing opening acts for bigger bands, colloquia are like the big shows at downtown venues. Think the Troubador in LA, or the Great American in San Francisco (sorry, I don't know the big venues on the East Coast!). They are usually held at the end of the day on a Wednesday or Thursday, right in the heart of the week. Not the end of the week when people might take off early for a long weekend, or the beginning of the week when people are returning from weekend travel. There's usually a "tea time" before the talk consisting of Costco cookies, coffee, maybe some wine and cheese. After eating and drinking, a large fraction of the department gathers for the big talk of the week: 45-55 minutes followed by 5-10 minutes of Q&A.

Another big part of giving colloquia are the meetings you get to have with various people in the dept before and after the big talk. These are usually 30-60 minute chit-chat sessions during which you talk about your research ("tell me something you won't cover in your talk"), ask about their research, and maybe even get a lab tour or two. These are great opportunities to learn about exciting science outside your field, put names to faces, and have your face put to your name. Colloquium visits also usually involve a lunch date with the grad students, and a big post-talk dinner out at a fancy local restaurant. These dinners are where you get to hear all of the good gossip, catch up with old friends and enjoy good food and good drinks. Think: the post-show part in green room.

I'm becoming more and more convinced that these colloquia engagements are a vital part of one's career development as a young scientist. I'm learning a lot about others research, other departments' approaches to teaching, meeting interesting people in my field, gaining a lot of public speaking experience. Plus, people are learning a lot about me, my research and what I'm up to over here in Pasadena.

At the same time, all of this travel has its cost. It leaves Erin home with the kids for long stretches, I miss my kids, it takes me away from my students, and it's not easy to do research on the road. So after two solid years of monthly speaking engagements, I've decided to take a long stretch off from traveling. It's going to be a good summer home with the kids, lots of hands-on advising, weeks at a time to do my own research, and I even plan to take a 3-week vacation!

This is also a good time to look back. For my own records, if not your entertainment, here's where I've traveled in the past two years. Think of it as the JohnJohn 2009-2011 US Tour:

That is one long set of tour dates, rock star! Found you in the bottom photo, Waldo...the gal in front of you looks like she had a hangover :)
When will your tour bus come to Rice or someplace close to Texas? any colleges here do astronomy?

Nice!

Also, you said Costco cookies and now I'm having flashbacks to Wednesday seminars in grad school.

So non-conformist... where's your name tag?!! :)

Any talks lined up in the Southern Hemisphere?

An annual note to all the (NSF) haters

It's that time of year again: students have recently been notified about whether they received the prestigious NSF Graduate Student Research Fellowship. Known in the STEM community as "The NSF," the fellowship provides a student with three years of graduate school tuition and stipend, with the latter typically 5-10% above the standard institutional support for first- and second-year students. It's a sweet deal, and a real accellerant for young students to get their research career humming along smoothly because they don't need to restrict themselves to only advisors who have funding: the students fund themselves!
This is also the time of year that many a white dude executes what I call the "academic soccer flop." It looks kinda like this:


It typically sounds like this: "Congrats! Of course it's easier for you to win the NSF because you're, you know, the right demographic." Or worse: "She only won because she's Hispanic."…

Culture: Made Fresh Daily

There are two inspirations for this essay worth noting. The first is an impromptu talk I gave to the board of trustees at Thatcher School while I was visiting in October as an Anacapa Fellow. Spending time on this remarkable campus interacting with the students, faculty and staff helped solidify my notions about how culture can be intentionally created. The second source is Beam Times and Lifetimes by Sharon Tarweek, an in-depth exploration of the culture of particle physics told by an anthropologist embedded at SLAC for two decades. It's a fascinating look at the strange practices and norms that scientists take for granted.
One of the stories that scientists tell themselves, whether implicitly or explicitly, is that science exists outside of and independent of society. A corollary of this notion is that if a scientific subfield has a culture, e.g. the culture of astronomy vs. the culture of chemistry, that culture is essential rather than constructed. That is to say, scientific c…

The Long Con

Hiding in Plain Sight

ESPN has a series of sports documentaries called 30 For 30. One of my favorites is called Broke which is about how professional athletes often make tens of millions of dollars in their careers yet retire with nothing. One of the major "leaks" turns out to be con artists, who lure athletes into elaborate real estate schemes or business ventures. This naturally raises the question: In a tightly-knit social structure that is a sports team, how can con artists operate so effectively and extensively? The answer is quite simple: very few people taken in by con artists ever tell anyone what happened. Thus, con artists can operate out in the open with little fear of consequences because they are shielded by the collective silence of their victims.
I can empathize with this. I've lost money in two different con schemes. One was when I was in college, and I received a phone call that I had won an all-expenses-paid trip to the Bahamas. All I needed to do was p…
