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.
Happy to have you! The science behind MRI is fascinating, and the machines themselves are really cool. Have you ever seen a magnet quench? I don't think they're really supposed to happen during normal operation, but some of the videos I've seen have been rather dramatic.
It is pretty crazy people were able to figure that all out and we are able obtain crazy detailed pictures without radiation.
No I haven't seen it! Hoping to see a controlled quench someday but also hoping to avoid needing to use it in any emergency situations; it'll have to be a damn near life/death situation to hit that button. Very costly decision. I guess there's also a dwindling supply of helium in the world so that could get interesting as time goes on.
Yeah, helium being a finite resource was something that really surprised me when I first learned about it! Better to keep it inside the MRI as much as possible for sure
helium recovery and recycling has come a long way, and the costs of helium are now justifying the extra expense of the hardware, so I think that problem should abate somewhat in the coming years.
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.)
Raman and EXAFS/XANES are techniques to probe different types of molecular transitions. Vibrational raman probes molecular vibrations, and XANES probes electronic transitions due to excitation of core electrons. Each technique will help you obtain different molecular properties. The standard approach is to apply these methods to do "static" absorption studies, meaning that one studies the transitions induced by these light sources in order to obtain molecular information of a given sample. The time-resolved techniques expand these measurements along the time dimension, so you can measure these properties but in a sample that is changing extremely quickly in response to a trigger (usually light).
So, it is not that the technique is a cross between these, but rather an approach to take Raman, or XANES, or IR-spectroscopy, or UV/Vis absorption spectroscopy, and then apply it in a time-resolved manner. You can usually take any spectroscopy technique and add "time-resolved" at the beginning and you will find someone doing that. Of course, some techniques are easier to perform in practice than others. I have done some time-resolved XANES experiments, and for those we need to go a synchrotron and the experiment is really tricky. A time-resolved UV/Vis can be done in many university labs. I don't have practical experience with Raman experiments.
That's a really clear explanation, thank you!
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.
That's a field where it seems (to an outsider) like a lot has been happening recently! Glad to have you here!
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.
I work in mine closure. I create plans to re-integrate them back into the surrounding landscape, and provide valuable end land uses (not just those centred around ecosystem re-establishment).
That's so cool! Sounds like an incredibly rewarding job. (Also I love visiting old mines that are no longer working but are open to the public for viewing. Always a cool experience.)
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.
Best part of it is being able to code functionality then sit down inside an actual physical vehicle and see, hear, and feel it act out what you programmed. Incredibly satisfying.
working in a cultivated meat startup, msc in biotechnology, but now disillusioned and wanting to do something academic/more down to earth and helpful
If it's not too personal, may I ask what lead to your disillusionment with the field? "Lab grown" meat (assuming that's what you mean by cultivated) has seemed like a promising idea to me for a while, in terms of environmental impact and the ethical consideration of animals.
I work at a company that makes large and small rocket engines (e.g., the ones on SLS/Artemis, and solids for a number of defense programs), and various electrical power systems (e.g., for the ISS and some of the Mars rovers). I manage the space software engineering organization.
Look at this rocket surgeon, over here. SMDH.
I'm just a software/systems guy; I work with a lot of genuine rocket scientists - they're fun to work with.
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!
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.
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/
I'm a software developer who works on Backend/APIs/Cloud/AI.

Some days just turn out that way lol
I'm a PhD candidate in inorganic and biochemistry! Loving the chem representation here, and loving OP's username.
I'm a professor of chemistry, I mainly do organometallic research but we've been branching out into other areas.
@realChem I retired from being a chemical engineer in the environmental remediation of hazardous wastes and petroleum. Went sailboat cruising, and stopped along the way to teach high school chemistry four years. Now I volunteer with OpenAir Collective working on CO2 removal (from atmosphere, not point sources - later is called "capture" instead of "removal" for some reason). Without chemicals, nothing would exist!
I actually did chemical engineering as my undergrad degree! I didn't work directly on any remediation projects, but one of the first jobs I had involved making sure all the waste our plant produced was properly treated. It was a slurry, I was helping to separate all of the solids and then neutralize the remaining liquid, and then it went on to Clean Harbors for final treatment.
Your whole post-career honestly sounds ideal, I hope to do something similar. I've always wanted to teach, but after I retire and don't need the money.
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.
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.
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
I'm a Mechanical Engineer who designs automation equipment. Basically lots of 3-6 axis robots, multi-axis gantries, various conveyance mechanisms, and other specialized automation equipment integration. Its fun because it is a job all about things moving from point A to point B.
I have my PhD in physics with a background in material science and primarily work in Pharma developing early stage biologics programs (antibodies, gene therapies, etc). That means basically any of the molecules I have worked on are maybe 5+ years away from reaching the market. I don't meet many other physicists in this field, instead it is primarily chemical engineers and biochemists. Even working in industry, I still have the chance to publish and attend conferences though.
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.
PhD candidate, archaeologist in a physical geography department. I read dirt to reconstruct ecosystems over time.
I studied environmental science as a major and am working in hazardous waste site remediation, water and wastewater treatment, and dabble in assisting some civil engineering projects.
@Knickknack @realChem I graduated in chemical engineering back in '83 and found myself in wastewater treatment consulting. I gradually transitioned to industrial wastewater and then hazardous waste remediation. It was a good gig! Retired in 2001, so it has probably all changed quite a bit. Good luck to you!
That's so cool, and thank you. I often think I would have loved to study a chemistry or engineering discipline, if I had been more in touch with my abilities and interests as an 18 year old starting college. I did complete what was a newer degree at the time called environmental technology, and it was geared toward renewal energy technologies with a lot of various science based courses as backbone. But certainly, the industry has changed a lot even in the time I've been involved, starting as a hazardous waste site remediation project manager for an environmental consultant, then got water and wastewater treatment licenses in 2005 when I saw an opportunity to get in on an emerging sector in the company I was working for. Right now the industry is struggling for licensed professionals, even while regulators push ahead in requiring more and more use of the technology. Should be interesting to see how it develops over the coming years. Overall though, I had been very fortunate to truly enjoy my career and the industry I work in.
@Knickknack I volunteer with openaircollective.cc - focused on carbon dioxide removal, speaking of emerging sectors. It is all volunteer, and a good way to follow the burgeoning climate change mitigation realm. I'm using a lot of what I learned over the years in business to develop a wiki there: https://openairforum.org Come by some time!
Hey you know what? I saw a post about this yesterday (it was probably you!) and thought it sounded like an incredibly valuable pursuit. I will definitely check it out, thank for the links.
That's very cool! One of my friends in undergrad did a co-op working with a wastewater / hazardous waste treatment company. It seemed like a surprisingly (to me at the time) vibrant field, with lots going on!
It's good to hear about people giving the industry a try! There is really so much career opportunity, and it's not going anywhere. I've weather multiple recessions, housing crises, economic booms and downturns in this industry and it is just steady, because it is so essential. I hope more people consider it as a career because the field is suffering for lack of licensed professionals.
Social sciences, expert/consultant position. We have our own in-house research, and collaborating with them is always good fun
I work a day job in IT, have a side business doing IT, work an occasional shift at my buddy's liquor store, and sell furniture on the side.
