Spring in Chicago

Whilst I spend most of my time in the city now, since I work in the Pritzker Lab at the Field Museum labs instead of at the Arboretum, I do work at the Arb on Thursdays. During this time I’ve been analysing the data gathered from biomass and vegetation indices in R, working on a potential paper. I’m quite proud of the various graphs I’ve made, utilising the “ggplot” package. Since this is a group effort, we’ve taken to using GitHub to streamline our workflow. Although I’ve used GitHub to access other people’s data before, I’ve never used it to upload my own data and collaborate with others. The process has been largely straightforward and we’re making good use of the system.

I made an exception to my usual schedule the other week when I worked at the arboretum on Monday. This was because there wasn’t just any Tree Talk happening, there was a Super Tree Talk. Presented by Nathan Swenson from the University of Maryland, this talk was on the structure and dynamics of tree assemblages, from traits and phylogenies to transcriptomes and functional phylogenomics. Back at the Field Museum, I’ve recently also attended talks on indigenous archaeology and the root microbiome.

Just down the road from the Field Museum is Adler Planetarium. I’d never been to a planetarium before until a few weeks ago when I went to “Adler After Dark” with Diana. As you might suspect, the event was in the evening, at a time when the planetarium would usually be closed. Although there was a theme (game-night), we’d never been to the standard exhibits or shows, so those were the priorities of the evening. The two shows we saw were on the “Cosmic Wonders” of the observable universe and of the sky as seen from Chicago on that night. The first showed the many deep sky objects humanity has observed, including the incredible photo of 5,550 galaxies from Hubble’s eXtreme Deep Field, featuring galaxies formed just 450 million years after the big bang, and a photo of gravitational lensing on a galactic scale. The second pointed out the many asterisms and constellations visible in the night sky. We also were given a tour of the telescope and got to turn the roof – very fun. That night also marked the second time I’ve held a piece of the moon and Mars!

Back on Earth, I had a Skype meeting with the Tree Charter’s Student Council – a group I was chosen and have been volunteering for since early 2016. The organisation, which is affiliated with the Woodland Trust, are partnering with NUS to engage Students’ Unions around the country. I’m very excited to continue working with them in the future.

New England Thoughts

Although I’m working at the Field Museum most days, I still work at the arboretum on Thursdays. The main purpose of this is for the individual and group lab meetings, but it’s also a good time for me to focus on analysing the data from the prairie restoration project, this includes the biomass data I collected in autumn, as well as NDVI and soil data collected previously by Lane and other researchers. Towards the start of the month, Andrew and I sat down and worked through the data, analysing the NDVI readings from one section of the experiment, with particularly deep soil, to their replicates in other sections. Later in February, I cleaned up the code and set aside what worked, making use of RStudios notebooks that use markdown – I’m finding them very handy. Next up is checking to see if the results observed from the NDVI data are reflected in the biomass data.

Working in R again got me thinking back to second year, when myself and Heather tackled a small research project during our Research Methods module. Our study was on leaf morphometrics and involved ~80 samples from 6 sites. This, of course, pales in comparison to a full dissertation but was a very useful intro to the world of research. My dissertation next year is still something I need to be thinking about, as are my module choices for third year. Currently, BSc Genetics students only have one optional module in their final years, making this decision particularly difficult – I’m considering at least 4 modules right now.

In the middle of February, I took a trip over to New England, specifically Mount Holyoke College, to visit some friends. Although I didn’t get to see much of Boston, Massachusetts seems like a beautiful state and reminded me more of home than anywhere else in the US so far. Mt Holyoke College is also remarkable, being a fairly old women’s college that features grand brick buildings and a variety of trees, such that they form the Talcott arboretum, which accompanies the Mt Holyoke College Botanical Garden (which has a corpse flower!). It was nice to hear that they’re also a progressive women’s college, accepting trans and non-binary students – perhaps unsurprising considering the college’s LGBT history. The nearby town of Northampton (or ‘Noho’) even features a rainbow zebra crossing. Everyone I met was friendly and welcoming, letting me join them in some interesting lectures and also indoor rock climbing – something I’ve missed doing whilst being over here.
