Name: Giorgio Orlando
Current position: Postdoc
Affiliation: University of Groningen
Field of research: Cosmology, with some interest for Astrophysics and particle-physics.
What is your career trajectory to date?
I got my Phd in University of Padova in February, 2020. I remained in Padova as a postdoc until September 2020. Then I moved to the University of Groningen for another postdoc, which is my current position.
What are the most exciting open questions in your research area?
To me, it is the discovery of gravitational waves from inflation.
What do you like and dislike about being a scientist?
I like the constant challenge of solving new problems, getting new ideas and being rewarded by developing them. I dislike the frustration in discovering that an idea and months of hard work might bring to nothing in the end.
Which of your skills are you most proud of, or find most useful?
I am proud to be patient, resilient and honest. I always try to be a good example for people younger than me and do the right thing, rather than being opportunist.
In your career so far, at what point were you the most excited, and what were you excited about?
Difficult question. I don’t usually get excited for my achievements. I must say that I got very excited when I ended my PhD!
What new skills would you like to learn in the next year?
There are a lot of things that attract me, also outside my research area. But among all the things, I would like to learn to deliver my research to the generic non-expert public.
What advances or new results are you excited about or looking forward to?
The launch of the next generation of gravitational waves missions, like LISA.
What is the biggest obstacle that is slowing down your research field right now?
The difficulty in finding very new and original ideas. My impression is that cosmologists tend to over-publish the same thing, rather than risk an high-reward high-risk scientific path. So, basically, the "publish-or-perish" road.
What’s your favorite food?
It depends, sometimes pizza, sometimes sushi, sometimes chilli chocolate ice cream.
How do you like to relax after a hard day of work?
Cuddling with my girlfriend, seeing Netflix film/YouTube videos. Playing football.
Do you have any non-physics interests that you would like to share?
I like helping people with mental illness or personality disorders. I like playing football.
If you were not a scientist, what do you think you would be doing?
Difficult question. Maybe I could have been a good psychologist, but at the same time I don’t think that psychology is really rigourous. In any way, something in connection with people that struggle with mental health.
What do you hope to see accomplished scientifically in the next 50 years?
If it refers to my field, I would say the discovery of the nature of dark matter or dark energy. Outside my field, I would hope that medicine could cure or give relief to people with terrible diseases, like permanent paralysis or cancer.
What question would you have liked us to ask you, and what would you have responded?
“Are you happy?” Fortunately, I am surrounded by people who make me happy.
Name: Oindrila Ghosh
Current position: PhD
Affiliation: II. Institute for Theoretical Physics, University of Hamburg
Field of research: Astroparticle Physics and Cosmology
What is your career trajectory to date?
I am currently in the final months of my PhD in astroparticle physics at the II. Institute for Theoretical Physics, University of Hamburg (DESY) and will soon move to the Oskar Klein Center for Cosmoparticle Physics at Stockholm University as a postdoc. Prior to this, I did my masters in astrophysics and cosmology from the Institute of Cosmos Sciences, University of Barcelona and in particle physics from The Institute of Mathematical Sciences, Chennai where I was a junior research fellow.
What are the most exciting open questions in your research area?
Some of the pressing questions of my generation and those before have been understanding the nature of dark matter and dark energy. Another very interesting question has to do with the origin of the ubiquitous cosmic magnetic field: is it astrophysical or primordial?
What do you like and dislike about being a scientist?
In contrast to my professional experience outside of academic science before, I absolutely enjoy some of the unique perks of being a scientist: the pursuit of knowledge as a force of public good as well as waking up excited to face every day with curiosity and a strong sense of purpose.
As someone with intersectional identities and little representation in my field of work, it is often difficult to establish and maintain a sense of belonging. To top it, lack of financial stability, hypercompetitiveness, hierarchical structure of the profession, and immigration bureaucracy do not make things easier.
Which of your skills are you most proud of, or find most useful?
I am pretty nifty at being able to zoom in in order to get into the details of a problem and zoom out when necessary, connecting seemingly unrelated concepts to find new ideas and eventually stitching a holistic perspective together.
In your career so far, at what point were you the most excited, and what were you excited about?
The Higgs discovery made quite an impression on me as I was starting to study particle physics at the time. I should also mention the joint Planck and BICEP2 results which generated a lot of excitement in 2014, and eventually were attributed to galactic dust rather than primordial gravitational waves. That was a lesson on cautious optimism for me!
What new skills would you like to learn in the next year?
The past pandemic years have made it difficult to interact meaningfully within the community. I want to cultivate my people skills in the coming year as much as I want to implement new computational techniques in my field of research.
What advances or new results are you excited about or looking forward to?
I am most excited about what the ongoing and future searches of axions and axion-like particles will reveal. I am also very much looking forward to how the first results from JWST can help us understand the seeding and growth of supermassive black holes.
What is the biggest obstacle that is slowing down your research field right now?
People not talking to each other (enough), i.e., lack of communication among disciplines. For example, if particle physicists had more coffee with astronomers across the globe, keeping our differences in how we do science aside, we would move much quicker. However, in addition to new discoveries and getting more funding to do science, we may have to bear the side effect of stranger and stranger acronyms!
What role do you think a community network like EuCAPT can play in developing theoretical astroparticle physics and cosmology in Europe?
The common notion is that experimentalists work in large teams over a long timescale, and theorists, in contrast, work mostly alone or in small short-lived collaborations. With EuCAPT, this notion is challenged, and theorists across career ages not only do find themselves in a platform to communicate ideas with one another but also have the opportunity to join forces to persuade national and European public stakeholders to turn some of our “bold” visions into real experiments and more broadly, influence policymaking around theoretical astroparticle physics and cosmology. With its current strength in numbers and effort in community building, the network holds the potential to grow into a democratising force in how knowledge is valued, conserved, and exchanged among peers within Europe.
What’s your favorite food?
This is probably the hardest question to answer. I have a weak spot for rustic home-cooked Mediterranean food but my favourites come from the two beautiful food cultures I have had the privilege to experience from the inside. The first would be Daab Chingri, giant Bengali freshwater scampi coated in mustard oil, mustard paste, green chilies, unripe mango, and young coconut pulp, and then baked inside a tender coconut. The second are freshly foraged fragrant wild strawberries (smultron in Swedish) with cream made from farm-fresh raw milk, a summer treat from the countryside.
Have you lived in a different European country than you do now? If so, would you like to tell us something about it, e.g. a fond memory or something you found surprising?
I lived in Spain and Sweden before. The meal times could not be more different. For perspective, the dinnertime in Catalonia roughly mimics that of my tropical homeland, which is anywhere between 9 pm and midnight. In Central Sweden, on the other hand, dinner is served during 4-7 pm, literally known as mid-day meal (middag). The contrast seemed very amusing along with the dramatic variation in daylight hours depending on season.
How do you like to relax after a hard day of work?
Playing cricket a few evenings of the week! I am still working on my off spin but you won’t regret putting me towards the beginning of your batting lineup.
I cook a lot, seasonal and local when possible, and am always open to new culinary adventures: an obscure ingredient, a demanding technique, or a counterintuitive order in preparation.
Singing Hindustani classical and Bengali folk music have been a big part of my life and still is.
Do you have any non-physics interests that you would like to share?
I am a giant foodnerd and have travelled across the globe to eat my way through understanding the axes of tradition, craft, culture, and sustainability in various communities. I am also a passionate science communicator and currently host the STEMme Podcast that I created with my colleague Philine, where we discuss latest developments in different scientific fields and interview other scientists on their scientific work.
If you were not a scientist, what do you think you would be doing?
I would have been a poet or a filmmaker or both. I published a chunk of my creative writing and did public readings during my teen years, which showed me how profoundly words can affect human beings in real time. I still hold the passion for cinema and make documentaries during my time off physics.
What do you hope to see accomplished scientifically in the next 50 years?
Aside from closing in on the nature of the dark sector, I hope to witness the discovery of primordial gravitational waves, or in its absence, the development of a successful theory describing the early universe.
Name: Alex Jenkins
Current position: Postdoc
Affiliation: University College London (UCL)
Field of research: Gravitational wave astronomy
What is your career trajectory to date?
I did my BA and MSci in Astrophysics at the University of Cambridge (2013-2017), before moving to King's College London for a PhD in Theoretical Physics (2017-2021), supervised by Mairi Sakellariadou. Last September, I joined the Astrophysics group at UCL for my first postdoc position.
What are the most exciting open questions in your research area?
Too many to list! How did the Universe begin, and how did it end up the way it is now? How do we unify gravity with the other fundamental forces? What is the true nature of dark matter and dark energy?
What do you like and dislike about being a scientist?
I love having the freedom to pursue what I find interesting, being able to think creatively, ask questions, and learn new things. I also love the opportunities to travel and to interact with lots of interesting and intelligent people. The main downsides are the competition for jobs, the lack of job security, and the expectation that you'll relocate every few years.
Which of your skills are you most proud of, or find most useful?
I think I'm pretty good at explaining scientific ideas in an accessible way - whether that's in teaching, in public outreach, or in giving talks to other scientists.
In your career so far, at what point were you the most excited, and what were you excited about?
I will always remember LIGO's announcement of the first gravitational-wave detection in 2016 as an incredibly exciting moment. I was in the final year of my undergrad degree, trying to figure out what scientific direction I wanted to take. From that day, watching the announcement live-streamed in a packed lecture theatre, I knew that I wanted to work on gravitational waves.
What new skills would you like to learn in the next year?
I'd love to develop my skills as a supervisor. I'm working with an excellent master's student at the moment, and am learning a lot about how to guide his research and give useful feedback.
What advances or new results are you excited about or looking forward to?
I'm currently very excited about a consortium I'm involved in, QSimFP, which is aiming to test our understanding of false vacuum decay using quantum analogue experiments in the lab. As a cosmologist, the idea of being able to tune parameters and repeat an experiment many times is very novel and exciting! Trying to understand these analogue systems is throwing up all kinds of deep and interesting questions, and I'm looking forward to trying to answer some of those questions once the experiment is up and running. (If you're interested, you can find out more on our website: https://www.qsimfp.org/)
What role do you think a community network like EuCAPT can play in developing theoretical astroparticle physics and cosmology in Europe?
I think organisations like EuCAPT are incredibly important, particularly in giving early-career researchers opportunities to expand their networks and share their work.
Have you lived in a different European country than you do now? If so, would you like to tell us something about it, e.g. a fond memory or something you found surprising?
I'm British, but I spent my teenage years living in the Netherlands. It's a great place to grow up. The thing I probably miss most is how easy and safe it is to get around by bike - much more so than here in the UK!
Do you have any non-physics interests that you would like to share?
When I'm not doing physics, I enjoy running around the parks, canals, and marshes of East London. I'm also a huge music nerd and occasional guitar player.
If you were not a scientist, what do you think you would be doing?
For a while I thought about becoming a teacher. I think helping young people achieve their potential and getting them excited about maths and science would have been very rewarding. Luckily I still get to do that now, in a slightly different way.
What do you hope to see accomplished scientifically in the next 50 years?
Detecting gravitational waves from the early Universe would be a huge accomplishment, whether that's with interferometers, pulsar timing arrays, or B-modes in the CMB (or even all of the above). I also really hope we can figure out sustainable nuclear fusion - but that's somebody else's job!
