In Harry Potter, when Voldemort attacks Hogwarts, the faculty didn’t have a dozen meetings to argue what to do. They knew just what to do.

So do you.

Largest magnitude alumni “gifts” to Yale:
$250M - Johnson
$160M - Bass
$100M - Broad Foundation

($180M/yr) - Vance and NIH

Just the facts here.

Through our careers as scientists, there have been and will be several challenges that arise. How we weather challenges and persevere is more important than the short-term losses.

Contact your professional network and reach out to support each other. We are in this together.

Kudos to the Grammys this year. Seriously talented folks.

(I have a 16 yo daughter, so I actually know some of the winners this year!)

Got vaccinated today (tetanus and shingles). Modern medicine.

Just search "pictures of tetanus and shingles victims" and you won't hesitate to get yours.

Landau–Levich Scaling for Optimization of Quantum Dot Layer Morphology and Thickness in Quantum-Dot Light-Emitting Diodes Quantum dot (QD) light-emitting diodes (QLEDs) are promising candidates for next-generation displays because of their high efficiency, brightness, broad color gamut, and solution-processability. Large-scale solution-processing of electroluminescent QLEDs poses significant challenges, particularly concerning the precise control of the active layer’s thickness and uniformity. These obstacles directly impact charge transport, leading to current leakage and reduced overall efficiency. Blade-coating is a prevalent and scalable solution processing technique known for its speed and minimal waste. Additionally, it allows for continuous “roll-to-roll” processing, making it highly adaptable in various applications. In this study, we demonstrate the precise control of blade speed in the Landau–Levich regime to create a uniform QD emission layer, using a commercial CdSe/ZnS QD as a representative example. QDs assemble into different morphologies on glass and the underlying layers of the QLED device due to variations in interaction energy. The QD film thickness can be modified from monolayer to multilayer by adjusting blade speed, which can be predicted by fitting the Landau–Levich–Derjaguin theory. The optimal speed at 7 mm/s results in a QD film with a surface coverage of around 163% and low roughness (1.57 nm mean square height). The QLED external quantum efficiency (EQE) of approximately 1.5% was achieved using commercially available CdSe/ZnS QDs with low photoluminescence quantum yield (PLQY), and an EQE of around 7% has been obtained using lab-made InP/ZnSe/ZnS QDs having a solution PLQY of 74%. All-blade-coated CdSe-QLEDs are further demonstrated by adopting the optimized speed for the QD layer. This method demonstrates significant potential for developing low-cost, reproducible, and scalable QLED technologies with uniform emission characteristics and low-waste production.

Proud of my minor part of a nice collaboration with the Reichmanis Group @lehighengineers.bsky.social on how to optimize QD-LEDs from potential roll-to-roll processes.

Congrats to graduate student Yiman Xu for leading the effort and engaging me on this cool project!

Similar for UGs doing research in my lab.

When I train them on image analysis, convincing them “images are data” has never been easier because their data on their phones are running low on space.

I still blow their minds on how to extract what they want. 😉

The Internet is so good for stuff like mutual aid and keep people informed amid crisis. Like, when I feel despair--and these days I often do--it's a small encouragement to be reminded that when we are proximal to suffering, we are capable of extraordinary generosity.

Sure, I'll sign up for everything that looks interesting!

Interviewer: can you explain this gap in your resume?

Chemical engineer: It can be made dimensionless by scaling it by dividing a characteristic length squared divided by diffusion (L^2/D) OR multiplying it by the reaction rate and dividing by a characteristic concentration (k/C).

We all have our versions of these. This one is a beauty!

Lunch for mentoring or simple collegiality has never been discouraged. In fact, I tell junior faculty they can text or call -anytime- they have a “weird” question when navigating academia. No judgement, only honest answers.
