Tip of the day: be a “deugeniet”. Very Flemish word for a mischievous / naughty rascal… but in a good way. And this summarizes Belgium 😎

Passive aggressiveness at Brussels airport… In case you didn’t know, now you know.

Looking forward to three days of discussing the introduction of renewables in the chemical value chain

Visiting the European Chemical Industry Council in Brussels to discuss pathways to a more sustainable future and transatlantic challenges. With a bit of luck, one day I might see the “Palace of Justice” without scaffolding.

Chemical engineering is a big deal in Belgium! First thing you see leave the airport 😎

Always fun to visit NY

Yesterday, following AIChE - American Institute of Chemical Engineers' 2025 Chemical Ventures Conference, I participated in a roundtable discussion with faculty, industry representatives, and venture capitalists at NYU. Great discussions on how to meet the current challenges for our profession

How’s your Saturday going?

Mandatory stop at UC Berkeley

My dealer in Palo Alto 🤗

On my way to Palo Alto 🤙🏻

The worst part of being an advisor is saying goodbye to great students. Thank you Margaret and Keira for spending the summer with us as REU students. Also a big thank you to @harshd1611.bsky.social and Sudipta for mentioning these two wonderful people in the lab!

Welcome @dankammen.bsky.social, who joins @jhu.edu Hopkins as the Bloomberg Distinguished Professor of the Just Energy Transition. A world-renowned energy scientist, Kammen is joining the Sustainable Transformations and Energy cluster. hub.jhu.edu/2025/07/29/d...

@deniswirtz.bsky.social are you still in Belgium 🤗

Always a pleasure to visit our collaborators at PPG headquarters in the beautiful and historic city of Pittsburgh.

Dear friends, After 11 incredible years at the University of Wisconsin-Madison I have decided to embark on a new adventure at @jhu.edu I am grateful for all the opportunities and the amazing colleagues from which I learned so much over the years. Excited about what lies ahead! Ive

Happy to visit SLAC Stanford

The US National Science Foundation could lose more than half its budget https://go.nature.com/4dMdIAZ

Fantastic defense by Edgard!

And this is just engineering!

Backstage moments before commencement madness kicks off…

Great day at the Michigan Catalysis Society hosted by GM. Always a pleasure to catch up with Eranda Nikolla.

Congratulations Unni!! After a great PhD defense, off to BMS in New Jersey! 💪🏻

Spring is trying hard in Wisconsin…

Brussels seems to be stepping it up. Introducing the fries tram.

Lord Ive enjoying London 😎

Lord Hermans during high tea 😎

Honored to be amongst the 2025 AAAS Fellows! Thank you to all people that contributed to this recognition and congratulations to all my fellow Fellows!

Adam Smith in Edinburgh and some good advice…

Edinburgh castle 🤩

London Heathrow here I come 😎

How do we loose selectivity in propane-to-propylene oxidation? Allylic H-abstractions from propylene, or our proposed epoxidation of propylene with vanadium peroxo species? We also propose a consecutive sequence of redox and acid catalysis with an alcohol intermediate! pubs.acs.org/doi/full/10....

Group retreat at Olbrich Botanical Gardens

A view of the famous Atomium, the Mothership of all Belgians, still on the ground in Brussels.

It was a pleasure to attend the academic session and retirement party honoring, Johan Martens at my Alma Mater KULeuven. One of the most inventive and entrepreneurial colleagues I know. Great catching up with old young friends, despite being heckled over the US trajectory…

Very grateful to our @scripps.edu President/CEO Pete Schultz, for this OpEd in @sandiegouniontribune.com on the key importance of research institutions in U.S. biomedical science and how federal support is critical to fuel new discoveries and medicines. www.sandiegouniontribune.com/2025/02/25/o...

Sliding into work 🤗

Imagine Hieronymus Bosch would be living amongst us today: inspiration all around!

But why would you still study history… 😏

Brooklyn

Early morning flight to NY

Landing in Chicago… Terribly cold 🥶

The struggle is real…

Midwest fun at O’Hare airport…

Delightful visit to Oak Ridge National Lab. Great applied catalysis work going on here! Also impressive neutron facility!

Victory!

On my way to Oak Ridge National Lab with 4 h delay. Finally made it out of Madison into Chicago 🤪

Hot from the press in Chemical Engineering Journal (CEJ): accelerating catalyst discovery with data-driven techniques.  Using Bayesian optimization, we efficiently navigate over 1 million possible formulations of Pt catalysts to accelerate serendipity 👉🏻 lnkd.in/gJKFpE3n
