I've been curious how many working researchers we've got in this community, and what you all do!

If you're working in science (physical or social), engineering, etc in a research capacity, give a shout in the comments and let us know what you work on! Same goes for students and amateur scientists at any level. (And by amateur I mean those of you who are working on your own experiments but just not being paid for it / not working on a degree; I'm upset that "amateur" has a negative connotation, it shouldn't.)

I'm currently a PhD candidate, working on transmission electron microscopy and electronic materials (mainly ferroelectrics). In the past I've been involved in research / product development in a few different industries, including medical devices, aerogels, and materials for RF devices.

I'm a PhD candidate too - my contract is finished now, but I am still writing my thesis. So I am currently at the awkward intersection of finishing a thesis and looking for a job.

My PhD focus is in applying time-resolved spectroscopic techniques to study the excited state dynamics of molecules. Basically, these are experiments in which a pulsed laser is used to excite the sample and a second probe light is used to measure a change in the absorption in response to the light. By measuring these changes in the absorption as a function of time, and applying quantum chemical methods to calculate the spectra of potential intermediates, one can sort of recreate a movie of what the molecule is doing after it absorbs light with a time resolution of femto to picoseconds. The materials that I study are organic dyes that are useful for microscopy, as well as molecules that respond to EUV light for applications in photonanolithography (for making the very small transistors in computer chips).

I am also an "amateur" scientist when it comes to biology, as many of my hobbies are nature-based and it's not like I can turn off the science bug when it comes to hobbies.

Well that's fascinating! The technique sounds a little bit like a cross between Raman and EXAFS/XANES? (Probably just because those are two techniques I happen to be familiar with though.)

I'm a research professor of neurology, and my research focuses on developing novel cognitive assessments for measuring early-stage Alzheimer's disease and other types of dementia.

[-] realChem@beehaw.org 2 points 1 year ago

That's a field where it seems (to an outsider) like a lot has been happening recently! Glad to have you here!

[-] Dr_Cog@beehaw.org 4 points 1 year ago

You'd be correct! The new anti-amyloid drugs are very exciting, and it makes my work on preclinical Alzheimer's even more fulfilling as it can have a real impact on getting people tested and treated as early as possible.

[-] TheAlrightGatsby@beehaw.org 3 points 1 year ago

PhD in Geology. Now am a research scientist working in more general materials science/chemistry/gas adsorption. My thesis was on lunar petrology where I studied Apollo 16 samples. My current research is much less exciting. Haven't touched a rock in ages and my geologist heart hurts from it haha

working in a cultivated meat startup, msc in biotechnology, but now disillusioned and wanting to do something academic/more down to earth and helpful

[-] CanadaPlus 2 points 1 year ago

That doesn't feel helpful to you?

[-] appel@whiskers.bim.boats 2 points 1 year ago

no, the technology is underdeveloped, and very resource intensive. I don't think it is a viable alternative at all. Better to just eat what grows from the ground than spend so much time, money, energy forcing cells that don't want to grow in such an artificial environment. I've also started to notice how it seems to be quite tied to EA and longtermism crowd, who are investing in it a lot.

I’m working on my Astrophysics PhD. I study “galactic cannibalism” aka how galaxies grow and change by eating smaller galaxies. My big focus is on teaching and outreach though rather than research.

I'm a professor of chemistry, I mainly do organometallic research but we've been branching out into other areas.

[-] realChem@beehaw.org 1 points 1 year ago

Very cool! My only experience with organometallics is with CVD and related technologies (like we've got one machine we use called a FIB – focused ion beam – that uses an organometallic as a carrier for platinum deposited as part of the process). Mainly I think of them as "probably toxic, probably pyrophoric, treat with extreme caution" sorts of chemicals.

[-] saltysel@sh.itjust.works 3 points 1 year ago

It's science-y enough but I'm definitely not considered a scientist so much as a technologist. I work as a MRI (Magnetic Resonance Imaging) Technologist. Previously a X-Ray Technologist.

My machine does all the science for me but it's a pretty neat concept. Using magnetic gradients and RF pulses at hydrogen protons to acquire accurate digital imaging.

Development engineer working with autonomous vehicles. Worst part of it is having to interact with Tesla bros who think that they have self-driving figured out despite what experts in the field tell them.

I'm an associate professor in computer science, currently working on stochastic algorithms (like genetic algorithms).

Until now, I've been working on quite abstract optimization problems, but I'd like to switch to more useful applications, like social inequalities or climate change.

[-] realChem@beehaw.org 1 points 1 year ago

I get that. Working on a more abstract problem should, in theory, help solve more practical problems down the line, but sometimes it just feels less satisfying that working on something where you can see the real world application and (hopefully) results. I'm definitely looking to do something practical with my experience once I'm finished with my PhD.

I'm a Data Scientist (physics PhD) for a large enterprise company. I've been in this field for the last decade and I'm kinda bored with it. I'm not exactly sure what to do next though....

[-] realChem@beehaw.org 2 points 1 year ago

Mmm yeah, I can imagine things might get a bit stale after a decade working on similar things. What was your physics PhD in, something you'd be interested in pursuing again maybe?

[-] oofinsprouts@beehaw.org 2 points 1 year ago

My thesis covered optoelectronic measurements of nanomaterials for novel photovoltaics. Even as a kid, I wanted some sort of career researching alternative energy, but those jobs sadly don't exist.

I'm a postdoc, working on laser-plasma/ interactions and electron accelerators. My PhD work was on ultrafast electron diffraction.

[-] realChem@beehaw.org 1 points 1 year ago

ultrafast electron diffraction

That's pretty fascinating stuff! I know a lot about electron diffraction in general (in the context of TEM/STEM/4D-STEM), but not ultrafast. What kind of processes were you studying with that method?

[-] AcrossTheDrift@lemmy.one 1 points 1 year ago* (last edited 1 year ago)

Our beamline is still very new (my main focus was actually on building/commissioning it), so for now, we've just been looking at relatively simple processes like the Debye-Waller effect, where the diffraction spots become weaker as the temperature rises.

The ultrafast capability comes from the electron beam having a sub-picosecond duration, which essentially corresponds to the shutter speed of a camera. By varying the delay between a pump laser and the electron probe and observing the change in intensity of the diffraction spots, we can figure out how the heat deposited by the laser diffuses through the sample, and make a "molecular movie" of this process. It's in the same spirit as other pump-probe experiments, like what @Salamander does.

I’m a staff bioinformatics scientist at an academic institution, got my PhD a few years ago and wasn’t interested in a postdoc. I get to work on a huge range of research questions and lots of different technologies. It’s great!

[-] realChem@beehaw.org 1 points 1 year ago

Oh that's rad! What's it like being a staff scientist at an academic institution? I'm still trying to figure out exactly what I want to do after I graduate – I know I'm not interested in pursuing the tenure track, but I haven't decided if I should go back into industry / look into staff science positions national labs / etc.

[-] hamtooth@beehaw.org 2 points 1 year ago

It has its pros and cons — I work on lots of projects and help with parts of grant writing, but I’m not the one guiding the big research goal/question (I appreciate that the questions are interesting but don’t care that much about the question usually). Because I work on so many projects I usually only have <1 full day a week to work on each one, so progress can be slow and managing expectations can be challenging. I am paid more than a postdoc but less than I would in industry. It is expected that I will mentor undergraduate students and teach workshops. These things might make a big difference re: how much you enjoy the job. Folks in this type of position are sometimes called research software engineers: https://society-rse.org/

[-] realChem@beehaw.org 1 points 1 year ago

Huh, that's really interesting. I do like teaching, so that part sounds appealing (as does getting paid more than a postdoc!), so maybe it's a route I'll consider going forward. Thanks for your insight!

[-] LittlePrimate@feddit.de 1 points 1 year ago

I studied Biology and Computer Science, have a PhD in Neuroscience and now work in an Engineering department for medical devices, where I am still in contact with Academia through students working for us in different capacities. My main occupation is Software Tester, though. :)
