Had a great time reconnecting with folks and meeting new people at #ASLOSIL26! I also had a chance to share my work and some anecdotes about Mike Pace, one of my mentors who had a session honoring him. Thanks to the organizers for an awesome conference!

And that’s a wrap! I graduated with my PhD from UW’s Center for Limnology this weekend. I’m excited to stick around the CFL for a bit as a postdoc with Hilary Dugan working on some freshwater salinization questions. Going to celebrate finishing my degree by attending #ASLOSIL26!

I successfully defended my PhD last week! 🎉 I enjoyed sharing all I’ve worked on over the last five years, showing that #climate alters #resilience of lake primary production to short-term perturbations by weather and nutrients. I’m excited to stick around the CFL a bit longer as a postdoc!

When extreme events happen together or in sequence, their impacts can be catastrophic for people and river biodiversity. Whether that’s a flood following a drought, a drought and heatwave operating in unison, or a flood falling on saturated ground, the impacts of these compound events can multiply.
