When we were young

I grew up on the island of Guadeloupe (before moving to Saint-Martin.)

Since then, the kids I used to splash on the lagoon of Saint-Anne have grown quite a bit, and they’re now sharing the beauty of their islands and their many travels – enjoy!

I’m on bluesky social – it’s pretty quiet at the moment, come and join me!

It’s cold, I need you around me!

SFMOMA x Berkeley Lab: Hybrid forms

Yesterday I invited Tanya Zimbardo from the San Francisco Museum of Modern Art to give a talk at Berkeley Lab (details about the even can be found here: Hybrid Forms: Connecting Art and Science)

Tanya Zimbardo (SFMONA) at Berkeley Lab

It was quite interesting to hear her perspective on a topic which is close to my heart, and happy to hear many references to Rafael Lozano-Hemmer, who currently has the Techs-Mechs exhibition running at the Gray Area, but also quite surprising not hear anything about Jim Campbell (whose art glows atop the Salesforce building “Eye of Sauron”) or the work of Illuminate.

I’ve added a few old drone videos on youtube. Here are my favorites (the playlist is here)

How do you spell croissants

Finding the best croissants in the San Francisco is an essential quest. Here are a few great options:

  • Rotha (East Bay) – 1051 San Pablo Ave, Albany, CA
  • Arsicault (San Francisco) – 97 Arguello Blvd, San Francisco, CA
  • Marvel Cake (South Bay) – 1614 W Campbell Ave, Campbell, CA

I won’t dare to mention pastry shops that bake monstrosities such as Cronuts, Croffle or Croffin (there must beat cosmic justice, Mr. Holmes went down.)

I’ll take a minute to say a word about Bakesum (3249 Grand Ave,  Oakland, CA), a French pastry / Asian flavor fusion that started in Berkeley during the pandemic, very close to where I lived and brought me a lot of joy when I needed most.

A fabulous man

I watched The Fabelmans by Steven Spielberg, a beautiful tribute to the physicality of the movie making process.

I on the advice of my friend John Keitel (who lives in LA) and I was particularly struck by the invisible link between the “Ditch day” scene in The Fabelmans, and his short film “An All-American Story” (~1991), a tale of coming out in the 90s. It’s a a heartfelt movie, and an occasion to look at the progress we’ve made since – hopefully we’ll never go back to these days.

While we’re talking about memories on reel, I can only recommend you to watch Jonas Mekas’ As I Was Moving Ahead Occasionally I Saw Brief Glimpses of Beauty (streaming on Mubi), one of my all time favorite movies – over four hours of bliss.


Acronyms, I like acronyms!

Here are two resources that I found useful for (1) supervising researchers (SMART) and (2) mentoring scientists (TGROW)


(this is an excerpt from the Virtual Remote Mentor Guide -DOE-SC-WDTS Programs)
SMART is an acronym for a framework to help guide goal setting. It is intended to ensure that goals are planned, clear, trackable, and reachable. With SMART goals, you are more likely to achieve the goal efficiently and effectively. Below is an overview of the framework to establish SMART goals.

Life upgrade: I moved to Sausalito!

It’s pretty nice out there, living just across the marina, stand up paddling with my partner at sunset, and sailing through the bay on foggy days.

1000 days

Today is the thousandth day since the start of the pandemic, and we still haven’t figured out how to hold efficient meetings online.Here’s a useful resource:

Using machine learning to achieve diffraction-limited performance with x-rays deformable mirrors

In a our last paper, we present the use of machine learning to get the most of x-ray adaptive optics – and it works like magic! This was a great work accomplished by Gautam Gunjala, a grad student from UC Berkeley under a SCGSR grant, together with our wonderful colleagues from the Advanced Photon Source.

X-ray adaptive mirrors are very nice, because they allow to correct the shape of x-ray beams, when the beam gets distorted by mirror deformation or misalignment. That’s why we want to use them in the latest generation of synchrotron light source such as ALS-U or APS-U.
