The problem is not using the title or not, the problem is the asymmetry and the lack of respect that is embedded in how scientists from minoritized groups are treated

Em 2024 uma ONG evangélica estava capitalizando a atenção pra uma TAG nas redes sociais, escrevi uma thread revelando as ligações dessa ONG com lideranças que fizeram parte da pasta da Damares e do governo Bolsonaro. Há 2 anos estava enfrentando um processo por isso e perdi.

Hello all, meet Dr Sufia Hashim. She has just passed her PhD viva after a 5-hour grilling. Feeling proud! Left: with her supervisor (me); right: with PhD examiners (Prof Alexandra Olaya Castro and Dr Amelle Zair) #WomenInSTEM #Attoscience #StrongFieldPhysics

Hello all, there is an #AttoFridays talk this week. To join, you may register here: us02web.zoom.us/webinar/regi... or follow us on Youtube (www.youtube.com/@QuantumBatt...) #Physics #Attoscience

Posting here is like speaking to the void, but I will share this one. I dropped out of Opera in the1980s & my technique is far from perfect, but it is still fun to sing. This performance challenged a lot of stereotypes, I was told. Always happy to help 😜 #LedZeppelin www.youtube.com/watch?v=k1fb...

Yesterday, the @stand.earth team together with @amazonwatch.org @banktrack.bsky.social @oilchange.org, Parliamentarians for Fossil Free Future & incredible frontline leaders from across Amazonia hosted a dialogue on how public & private finance could protect the Amazon from fossil fuel extraction

In honor of Earth Day: a thread of environmental wins

Today is the day! Join us at 8:00 PM ET for our Virtual & Accessible Earth Day 2026 Rally to defend our planet, our health, and our future. Hear from lawmakers, experts, and activists leading the fight and find out how to take action. Register at this link: zurl.co/ZsB53 #EarthDay #EarthDay2026

There have been quite a few of those by now...and the YouTube channel is getting close to 1000 subscribers, which is nice! We will be around this Friday with another seminar #AttoFridays #QuantumBattles

Some flower pictures to clean the timeline. #Spring #EdenProject #Nature

I tend to wear Native American or African jewellery & my natural hair when running the #AttoFridays seminar series. Without making a fuss about it, this is a way to influence what is understood as "professional" or not. Here is a sneak peek from behind the scenes. www.youtube.com/@QuantumBatt...

Kuddos to the group project students I worked with this spring. They produced excellent work on chaotic dynamics within ca 2 months. Here are they presenting their poster!

Here r a few preprints/papers from 2026: 🧵 1) We (Sufia Hashim and I) assess two-electron quantum interference with more than one excitation channel. B/c the number of processes was too large for analytical conditions, we used statistical measures to compare images journals.aps.org/prresearch/a...

#TapajosVivo #Amazonia The fight continues, but it is important to celebrate our victories. 💚✊🏹

To register follow this link: us02web.zoom.us/webinar/regi... We are looking forward to this #AttoFridays season

Read the whole thread 👇🧵 Bringing all online was an insane amount of work for uni staff.

Que absurdo. E a cara de pau ha' alguns meses, durante a #COP30 foi de matar. Isso tem que parar #SOSAmazonia

Ainda falta revogar essa maldita lei, mas e' um começo. Fico insultada como a #Amazonia e' vista como uma colônia, seja por governos de direita ou de esquerda. E sim, estou de saco cheio de marxistas do sudeste falando no lugar das pessoas do Norte. E' uma farsa colossal! #SaveTheTapajosRiver

This destruction has been like this forever. #Amazonia is viewed as a colony to be plundered, also by many Brazilians. I was happy that the COP30 was in Belem, but I couldn't shake the feeling that our voices are never heard. What a farce! #SaveTheTapajósRiver #RevogaDecreto12600

The Tapajós River is not just water, it is memory, food, culture, and life. Sending so much love with the Indigenous people of the Baixo Tapajós who are currently fighting against dredging and all projects that threaten their future.

Bom dia 👇

I have really enjoyed this outreach event. It was great to be a speaker in the Physics Undergraduate Seminar at UCL, and talk to so many enthusiastic students with great (and unusual) questions. Hopefully I could be of help!

Here are a few pictures from Goa, India, to clean up the timeline. We all need that from time to time 😊

Had a great time at the 2025 IAMNOP in Delhi (plenary talk & session chair). It was great to see the pictures and meet the vibrant Indian Physics community. And yes, I look more and more like my paternal grandmother, lol.

When you are coming back from paradise and reality smacks you in the face. On Saturday, while waiting for my connection to Delhi. As a South American, this is particularly triggering. For more info see, e.g., en.wikipedia.org/wiki/United_...

2025 was about starting a new research area, renewal in many ways, and reconnecting with my Amazonian roots. It brought success, recognition, help from unexpected places, nasty surprises from collaborators and the necessity to realign myself once more. Happy New Year everyone, despite everything!

I wish all of you strangers a great holiday season with a festive enough picture. I will go offline soon, but not before leaving my best wishes. May 2026 be less weird than 2025, and treat everyone with more kindness. Take care!

Dear all, The #AttoFridays concludes on Friday 5th December 3pm London time with Dr Paris Tzallas on "Generation of optical Schrödinger "cat" states using intense laser-matter interactions and applications in non-linear optics". Register at quantumbattles.com/attofridaysp... or watch on YouTube

They are amazing & severely under-rated birds. I do online yoga with cats several times a week. It is not intentional in my case, but I am their tenant (or they view it this way)

Last #AttoFridays talk of the year - this Friday! Posters coming soon (we all have been insanely busy & run this on the side) Register here: us02web.zoom.us/webinar/regi... Or watch on YouTube - Live chat open for subscribers! www.youtube.com/@QuantumBatt... Seven missing to 900

This was a good #AttoFridays talk from a fellow Latin American who has been working with us for a while (available soon on YouTube once we get the OK from her). We will have one more talk in this season and will come to an end. #WomenInScience #WomenInStem #LatinasInSTEM

It’s impossible to watch #cop30brasilamazonia without feeling deeply connected. My family carries Indigenous ancestry, even if our ties are complex, we cannot name our people & are middle-class city dwellers. Enough of plundering #Amazonia and treating ppl from the North of BR as outcasts!

Absolutely worth a read. It exposes the greenwashing at #COP30 and shows that Indigenous people are deliberately excluded from key decisions. #Amazonia is seen as a colony within BR, which has been plundered for centuries.

Definitely worth a read - it's frustrating to see the greenwashing that is happening while the govt discussed oil drilling in the #Amazon Delta. #Amazonia has been plundered for resources and has been seen as a colony for centuries within Brazil. Indigenous ppl are left out of key decisions. #COP30

It's important to shine light on Belem & #COP30, but when I see this it reminds me of how Indigenous people are mostly left out of key negotiations. Belo Monte hydroelectric power station, for instance, destroyed the Xingu River and was pushed through during a left-leaning PT presidency.

This Friday - he has been doing great work on #FEL (free-electron lasers)

Dear all, The #AttoFridays continues on Friday 7th November 3pm London time with Professor Graham Worth on "Simulating Photo-Excited Processes using Grids and Gaussian Wavepackets". More details below 👇Register at quantumbattles.com/attofridaysp... or watch on YouTube

Hello all, I am back online, after an award ceremony & invited talk at the #FIOLS in the US. It was an interesting experience that went more smoothly than it could have been (grateful for this). One needs to find time to celebrate one's victories. Great to be back in London with my family.

Next #AttoFridays talk in 2 days. Still time to register (alternatively, you can subscribe to our YouTube channel; live Q&A is open to subscribers)

The #AttoFridays are back, on 10/10 at 3pm UK time. Our speaker will be Prof. Wendell T Hill (University of Maryland) & he will talk about "Rousing the quantum vacuum: ephemeral-pair dynamics on sub-attosecond timescales". Register here us02web.zoom.us/webinar/regi... Below is an abstract & bio:

There is so much evil in the world right now that I am sharing some nice pictures from the Amazon to clean up the timeline. These are from Marajó Island. Bom dia!

The #AttoFridays will start soon. Below is a sneak peek at the schedule. We will circulate Zoom registrations soon. Subscribers to the YouTube channel can ask questions via the live chat.

Dear all, I am back after some time in #Amazonia + some (longer than expected) recovery time. Below are a few impressions 🧵 1) Seminar at UFPA. The room was full of physics students. After 30+ years, it was a pleasure to return. I know where my bridges to BR will be, and I want to stay in touch.

Thought of the day: ``A gente tem que trabalhar muito para não ter heróis. Os heróis são uma denúncia contra nós. O herói só é uma pessoa extraordinária porque a gente não faz da causa que ele transforma em extraordinária uma ação ordinária. " Marina Silva (Brazil's environment minister)

I learned today from Rick Wakeman at BBC R4 that he played keyboards in Sabbath Bloody Sabbath & that Ozzmosis can be loosely classified as prog rock. I guess we will all miss the prince of darkness's shenanigans (I definitely will). Borrowing from Anne Rice, Ozzy was the damnest creature 😊 #RIPOzzy

One of the perks of being a scientist is to travel a lot. I have been in #Venice for an invited talk after a looong time.
