Find me in the machine shop or the mountains. Pumped about pumps. MIT MECHE PhD candidate.

@ALazurko @PhDVoice Real time do a pump efficiency-economic trade-off calculation on the whiteboard to back up a point! Crush it.

@mrtommyb I think we need to start #pandorasmallsat!

[Hilary Johnson @makerHilary]

👋🏼 physical community talking about virtual community. Thanks for hosting #ideocolab. Fantastic work @AmberAtherton

Comparing the drought monitor maps from this week 2023 and this week 2022. Even though I'm longing for California sunshine, I'm praying for even more rain! Now that we're refilling the aquifers stewardship is even more important.

Chase mode activated in an unusual place: the Bay Area! Heavy rainfall and winds spreading across the region and will continue into the night

Playing around with generative models, I asked #dalle2 for a self portrait. What do you think? #openai

Successfully defended my PhD at #MIT in @MITMechE on Adaptive Hydraulics for Improved Centrifugal Pump Efficiency. A hearty thank you to all my collaborators, industry sponsor @Xylem, @jwafs_mit, friends, and family for joining me on this grand adventure!

I took Negotiation Analysis at @MITSloan last week with Prof. Jared Cushan -- life-changing tools for work and life. This simulation https://t.co/GZOsyY88uL hits some of the key highlights. We learned to be nice, be clear, be provokable, and be forgiving.

I periodically check the U.S. Drought Monitor https://t.co/OCcI9jVFEI Its easy to forget about droughts when its colder, and we got 24" of snow this weekend in Boston. But there are many places in the US that are still considered severe drought...something to muse on.

Thought provoking tweets about the unexpected feedback loops and externalities of return on investment bas a driving force.

[Ryan Petersen @typesfast]

What caused all the supply chain bottlenecks? Modern finance with its obsession with "Return on Equity."

Sunrise flying into Chicago for a whirlwind day at #WEFTEC2021. Follow along as I investigate what's going on in the world of water 👇🏼 I'm asking the question: what is the future of water infrastructure?

[Hilary Johnson @makerHilary]

Thanks @DeepMind for making MuJoCo accessible to the community! I remember the first time I was trying to run a RL script and getting the error I didn't have MuJoCo.

[Google DeepMind @GoogleDeepMind]

We’ve acquired the MuJoCo physics simulator (https://t.co/knwXLZMr4L) and are making it free for all, to support research everywhere. MuJoCo is a fast, powerful, easy-to-use, and soon to be open-source simulation tool, designed for robotics research: https://t.co/Of3Q1W2GIR

Sinking into deep reading is easier in a place like this. Check out the air entrainment in an inlet vortex from pre-rotation in a pump. #turbomachines #pumps

@mahachanical Way to go Dr Haji and team!

[Hilary Johnson @makerHilary]

@mit_esi @MITMechE @AsegunHenry Congrats Alina!!

[Hilary Johnson @makerHilary]

@AoifeMFoley @MITMechE Great talk today. I appreciated your realism and focus on how tech, policy, and economics all need to come together to incentivize and make possible a greener (not net zero) future. I was taking notes the whole time and have lots of nuggets to simmer on. Thanks @AoifeMFoley !

[Hilary Johnson @makerHilary]

Excited to hook up my @Yokogawa flow meter, pressure transducers, tachometer and torque meter and start collecting data. #equipment #pumps

[Hilary Johnson @makerHilary]

Let's get this pump flow loop up and running. It's experiment time.

Pictured is a flow loop that tests pump operation and efficiency over a range of flows. I custom built this loop with the help of @XylemInc engineers to collect data on an adaptive centrifugal pump.

@NutterLaw @MIT @IP_Rory Thanks @nutterlaw @IP_Rory for your collaboration! It's great to work with you.

[Hilary Johnson @makerHilary]

@MITMechE @jwafs_mit Thanks @MITMechE!
