- Recent images from our SPIDERS pathfinder instrument demonstrating the self-coherent camera--next generation tech for direct imaging of exoplanets! We use a special coronagraph to interfere the starlight with itself, like a classic double slit experiment... [1/3] 🔭 #Instrumentation #exoplanets
- Thank you @fherwig.bsky.social!

- I learned today that am being awarded the J.S. Plaskett medal for most outstanding doctoral thesis in astronomy in Canada. Thank you @casca.ca.web.brid.gy, and my committee for the nomination! 🔭

- This is fantastic news. Upping grad and postdoc awards (both stipend and amount), and finally allowing non-Canadian/PRs to apply.
- 🚨 HUGE news from Canada's tricouncils who are harmonizing their scholarship & fellowship programs, upping the total number (huzzah!), and critically, allowing foreigners to apply for doctoral and postdoc fellowships. Want to work with me? Get in touch! 🇨🇦🧪⚒️ www.nserc-crsng.gc.ca/NewsDetail-D...
- Time for the promised thread on ε Eridani b! I should emphasize this manuscript is a submitted draft—comments from the community are very welcome. Bottom line: ε Eri b is likely a 1.0 Jupiter-mass planet, only 3.2pc away, on a 3.55 AU near-circular orbit, ~aligned with its debris disk. 🔭🪐🧪 [1/7]

- We've been cooking up some fun new results for the planet Epsilon Eridani b! Submitted and should be on the arxiv by Monday. In the meantime, here's a couple teaser figures :) 🪐🔭🧪
- Stabilized variational non-reversible parallel tempered sampling—this MCMC can handle just about anything you throw at it! pigeons.run 🧪
- Hah, I spoke to soon! Now accepted to AJ 🪐
- Perhaps a little premature since it's still under review, but I'd like to share a couple results from our preprint now up on the arXiv: arxiv.org/abs/2502.05359 🔭 We dive deep into the orbits of the binary brown dwarf companion 🪐 GL229 Ba / Bb newly discovered this fall by Xuan et al. [1/4]

- Very minor update to PairPlots that addressing some vexing typographical details in the margin credible limits. They now exactly match the font of the rest of the plot. Before VS after, plus multiple series now have limits printed. Yes, I’m probably a little obsessive…
- So I know the central limit theorem is a thing, but can anyone explain why my daily # of GitHub commits follow a normal distribution centred on Wednesday?? #GitHubWrapped
- 🧪🔭 Attending AAS in DC this January? Join us at our introduction to Julia programming for astronomy workshop! #julialang
- New version PairPlots.jl out now! We now calculate the effective sample size of your chains to determine the histogram binning and contour smoothing much more robustly. Before vs After:

- AAS scheduled my dissertation talk (20 mins) and contributed talk (10 mins) in the same 1.5 hour session. Probably no one wants to hear me speak that much back to back, right?! Should I cancel?

For more than 30 years, #Hubble has watched the shifting Uranian seasons, from southern summer solstice (seen by Voyager 2 in 1986), through equinox in 2007, and (hopefully) on to northern summer solstice in 2030. #planetaryscience 📸 NASA/ESA/STScI/Fletcher
- I got to meet real live astronaut Dr. Jenni Gibbons yesterday and give her a demonstration of our exo-🪐 imaging instrument SPIDERS! 🔭 #instrumentation
