Resources on writing and presenting

Scientist lean many things while they study their subject, but never formally learn how to make a good presentation. Here’s a few resources that can be helpful to get started.

Making a presentation to an audience is important to get your ideas through, and while communication is a basic human trait, communicating effectively requires some thoughts (TED talk speakers go through a thorough training to get their point across.)

Don’t trust Tufte, go for gold

Someone who has a good resource is Jean-luc Doumont – he’s a regular speaker at the lab and Stanford, and a contributor to Nature and other publications. Here’s a few resources available online: https://www.principiae.be/X0302.php
(maybe this video at 1.5x speed is a good start: https://www.youtube.com/watch?v=meBXuTIPJQk)
Another interesting speaker is Peter Fiske, who also made a few presentations at the lab; I’m enclosing his slides from some time ago (another interesting but unrelated talk by him is
Careers In Physics Workshop: Putting Your Science to WORK, about career perspectives, networking etc.)
In general, the workshops for postdocs are really good, and should be attended:

Here are a few things learned, for the use of postdocs where one can easily drown everyone else. These are based on my experience, but there are many resources around the web to draw from.

Some practical presentation rules 

(These are stretch goals; I rarely follow these rules myself, but they are useful if you don’t know where to start.)

Use 16:9 format (these days most presentations are online, and most screen are wide)

Start with an outline.

Often, using the title to summarize the main point of the slide is a good use of the title.

No text should be smaller than 18pts.

Use animations sparingly, to expose your thoughts point by point. Avoid fancy animation or transition between slides

No more than one slide per minute (if there’s more, you can probably merge a few points)

In one FEL swoop

“I suppose in about fortnight we shall be told that he has been seen in San Francisco. It is an odd thing, but everyone who disappears is said to be seen at San Francisco. It must be a delightful city, and possess all the attractions of the next world.”
― Oscar Wilde, The Picture of Dorian Gray.

Lately, many of my colleagues have been leaving DOE light sources (Berkeley Lab and SLAC National Lab) to work for startup companies, and it seems that they all try to build better sources (probably based on Free Electron Lasers.)

Such companies are Tau Systems, xLight and a third one which seems to be stealth but looks light a giant black hole, given the pool of talent it managed to attract.

Good EUV sources have always been a problem, and the current solution using laser pulsed plasma, blasting 40kW of CO2 laser power onto 100um tin beads at khz rates to generate ~200W of EUV is totally crazy, but it works. Still, there must be better ways to do it, and given the unit cost of a EUV litho scanner ($200M), improving the uptime and productivity even by a few percent would be extremely valuable…

I’m wishing good luck to my colleagues going his route, this is quite exciting!

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.

SMART & TGROW

Acronyms, I like acronyms!

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

SMART

(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.

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:

ALS-U CD-3

The Advanced Light Source upgrade project has received the Critical Decision 3, the very last step before we start building the facility – a $590M project for the US Department of Energy.

This is a great news for the facility, which will become the brightest soft x-ray light source in the world. I have worked on this project over the last five years, designing and simulating the new feature beamlines and developing new technologies to ensure optimal performance.

Penn State University (Fall 2022)

I had a great time at Penn State University, where I was positively impressed by the facilities and the people!

I mainly visited the Material Research Institute and the department of Astronomy and Astrophysics, where they are developing x-ray adaptive optics for space application together with NASA, for the Lynx project.

Thanks Susan Trolier-McKinstry for hosting me!

Angela Saini at Berkeley Lab

We were pleased, as Berkeley Lab Global Employee Resource Group co-chairs, to invite and co-organize with Angela Saini at Berkeley Lab on November 9th, 2022.

Alain sous tous ses Aspect

Alain Aspect just received an amply deserved Nobel prize in Physics – adding one drawing to my collection of Nobel Prize drawings

Drawing by Alain Aspect (2010)

I recall bumping on him at the cafeteria at Ecole Polytechnique back in the days, and asking him questions which he often dismissed in two sentences…

Incidentally, the last time I went there in December 2019 to visit my friend Franck Delmotte (Director of study at Institute of Optics Graduate School), he was just besides us.

How to get the most out of a conference in person

Making the most out of a conference is a good idea! My friend Maria Zurek (former Berkeley Lab postdoc, now at Argonne) made a very interesting talk, and here are her slide:

Maria Zurek (left) and I (right) with Jeff Welser (IBM VP of research, center) and the rest of the Berkeley Lab Postdoc Association in October 2019

She gave a few great pieces of advice, here are my favorites:
– come to the conference with your slides READY. If they’re not ready, you will miss most of the social hours, where the networking happens (that’s a hard one – but very true: a conference is mostly about meeting people, not presenting your research.)
