Let's get rid of Recommendation Letters. I'm grateful to everyone who wrote one for me (I assume >100 have been written). It makes sense early in careers, before you have a long C.V, but later, when your achievements are measurable, it just says if you stepped on toes or not(1/3)

Folks at @Matlab should really consider removing the "shading interp" command - it corrupts students and leads them into temptation.

Following current trends, the next PM will be in office for approximately minus 200 days

A high h-index implies that you work in a densely populated field with a lot of folks all working on the same thing and citing each other. This is therefore an index of how replaceable you are as a scientist. Discuss.

We have a postdoc position in my group! Goal is to answer simple Qs: What is the minimum energy required to erase an optical bit in finite time? And does quantum modify that bound? It's a collaboration with Chris Jarzynski at UMD. RTs appreciated : ) amolf.nl/jobs/postdoc-s…

Can we please make it a rule that a reviewer who says that a paper is not novel, but fails to provide even a single reference to any (whatever!) paper, should be automatically discarded by the editor?

Tomorrow (May 11 at 11:00 ET) I will give a webinar (hosted by the Photonics Detection and Photonics Metamaterials groups @ Optica) on metamaterial-based image processing. I will provide a tutorial/overview of the field, and discuss our recent results. optica.org/en-us/events/w…

remembered how a prof included a figure in a preprint (top, 2019) that is a near exact copy of a figure i published (bottom, 2015), but didn't think we should be cited cause "it wasn't really relevant" and "these are general ideas". both now published in the same journal. :)

If we continue on this path of madness in twenty years there will be no more academia. We will be all judged guilty of having fostered directly or indirectly this type of (increasing) toxic culture.

Our paper on how to design 4f-less, broadband, high-NA, high-efficiency and polarization-independent edge-detecting metasurfaces has been published in Nature Communications With Akshaj Arora Andrea Alu and Sahitya Singh CUNY ASRC Institute of Optics nature.com/articles/s4146…

👍👍Universities should not be real estate companies. "NY lawmakers will unveil legislation that would eliminate enormous property tax breaks for Columbia U. and NYU, which have expanded to become among NYC’s top 10 largest private property owners" nytimes.com/2023/12/10/nyr…

Excited to see our latest work published in Nature Photonics! We demonstrate metasurfaces that break Lorentz reciprocity and support asymmetric light propagation. Great collaboration with Andrea Cordaro Dimitrios Sounas Albert Polman Andrea Alu Institute of Optics CUNY ASRC AMOLF

Great News & Views article by Said R. K. Rodriguez and sander describing our recent Nature Photonics paper (Andrea Alu Albert Polman ) on heat-induced nonreciprocity, together with related work from Mikhail Kats 's group.
