Sofia Waissbluth graduated with a PhD in Experimental Surgery in 2013. She currently works as a medical doctor (specialized in otolaryngology) and a clinician scientist.

Q: What made you first interested in pursuing a PhD in surgery?

In my last year of medical school, which I completed in Chile, I traveled to Canada to do my elective internships at 看片视频. I did one month in dermatology and one month in otolaryngology (ENT). During that period, I learned so much, the teachers were great, and the overall environment was very good. The internships led to me meeting other people and expanding my opportunities.

One of the professors in the ENT department, Dr. Sam Daniel, has a lab called the 看片视频 Auditory Sciences Laboratory, which focuses on hearing loss. I鈥檝e always had interest in that area. He asked me whether I wanted to complete a Master鈥檚 program. I got the bug for research! I came back from Chile after I finished medical school and I applied for the Masters in Otolaryngology program and was accepted. Medical school in Chile finishes in December, so I started my Master鈥檚 the following January.

I started to do well in the courses and the presentations and my interest also increased as I knew more about research. My supervisor suggested that I fast-track to the PhD program. Because there is no PhD in ENT, I fast-tracked into the Experimental Surgery program because he is also a supervisor in that program. The PhD allowed me to do research at a higher level and establish relationships with other labs in collaborative efforts.听

Q: What kind of experiences during your PhD did you find particularly valuable?

The scientific method鈥攌nowing how to read an article, getting what you need, knowing how to create a protocol, knowing your statistics, and when to apply which method. The whole method has to be taught, it鈥檚 not obvious.

Q: Was your research more basic science research? Or was it more translational and clinical?

It鈥檚 basic science 鈥擨 didn鈥檛 do much clinical work in my PhD and that was on purpose. Basic science requires time, effort, a lab鈥攁nd you don鈥檛 always get those opportunities. So I put all my energy into basic science because I knew later on, it would be very difficult to do it on my own.

For example, if I don鈥檛 know whether X medication is toxic yet, I would have conducted experiments in an animal model. Then you have to start getting the animals and figuring out how to house them and who is going to feed them. I would need a lab tech and pay them. There are all kinds of limitations to doing basic science once you鈥檙e in the medical field. If you don鈥檛 have a grant, that鈥檚 a limitation. In the clinic, you could say you鈥檝e seen two or three patients with this condition and you believe you have a hypothesis that these patients could develop hearing loss. You could contact other doctors to send your patients, discuss it together. There鈥檚 more flexibility. It鈥檚 a little easier to conduct (except for RCT!). But for basic science research, if you don鈥檛 have a grant or you don鈥檛 have your own lab, it can be a little more difficult.

听Q: What was your main source of support during your PhD?

I was very lucky because my fellow PhD partners are also my friends. I keep in touch with most of them, because we spent time together, eating everyday together, doing our experiments together. It helps to have a good team because sometimes you鈥檙e doing collaborative work and helping each other. The human aspect is super important because I saw the same people every day for three and a half years. Many of my fellow PhD friends are also medical doctors in their respective countries. So we all have the medical background and we would share stories about the medical world. So that was nice. My family and friends were also a source of support.听

Q: Did having an MD background prior to starting PhD give you an advantage?

The advantage of having a medical background is that you see problems in the future and you think of it in a medical sense. For example, if something is toxic, I want to know exactly what level, if it could be used in children, if it could be used in certain complications of inflammation. Having that medical background leads your thinking towards translational work, I would say. It also provides insight into the 鈥渞eal world鈥�. For instance, some findings can be statistically significant but not clinically significant at all.听

Q: What kind of role did your supervisor play?

My supervisor had more of the laid back approach. If I had an idea and it made sense, he鈥檇 tell me to try it. We were able to do collaborative work, establish experiments, and do things that have never been done in the lab before. So I thank him for that because it gave us flexibility鈥攈e never restricted us or our ideas. I was able to use a lot of the facilities at 看片视频, and there are all kinds of things available like electron microscope and mass spectrometry. People will help you鈥攜ou just have to tell them your idea and people are receptive. So I would say that鈥檚 a big advantage of doing a PhD at 看片视频鈥攖here are a lot of facilities with a lot of knowledgeable people that are willing to collaborate and that is something that is amazing. You don鈥檛 find that in every university.

Q: What was your biggest challenge during your PhD?

Maybe one of the struggles is to make sure that when you have finished with the PhD, you have a coherent story that is not just one study after another, but various studies that have to make sense together, coherently, and tell a story. And you have to be able to create new knowledge.

Q: What鈥檚 your typical day like?

I am working as a medical doctor, an otolaryngologist. I completed my specialty in otolaryngology following the PhD. In the places I have worked, I鈥檝e been able to do all kinds of research鈥攎ostly clinical at the moment regarding hearing loss, which is what I鈥檓 interested in, and some prospective studies on children. I鈥檝e also done studies on patients who have certain conditions that predispose them to hearing loss, such as patients with osteogenesis imperfecta. I am a recipient of a research grant this year from The National Fund for Scientific and Technological Development (FONDECYT). This grant will allow me to incorporate some basic research into my daily activities.

Q: Is there anything that you wish you knew, like before you started your PhD?

I would tell myself 鈥淒on鈥檛 expect all experiments to work鈥�. You could have a hundred ideas and maybe fifty would work, or maybe not. There are a lot of things that people do, but they鈥檙e not published because it didn鈥檛 work. Maybe the dose was too high or too toxic or it wasn鈥檛 the right animal model or the right cell line. There鈥檚 all kinds of things that could go wrong, and it鈥檚 good to go in knowing that probably a lot of the experiments you will do may fail. And you have to take another approach and you have to be open, to expand on that and think about it, say why they didn鈥檛 work. What should I do? Should I change my model? Change this? You have to be able to do self retrospective analysis and not take it personal because it鈥檚 science.听For example, when I was doing scanning electron microscopy of inner ear cells, it鈥檚 the smallest piece of tissue. If you breathe near it, it鈥檚 gone! It has happened to me鈥擨鈥檓 exhaling and there goes seven days of work. You end up wasting material and wasting time, and you have to start over again. So it鈥檚 best not to get frustrated. These things happen to everyone! You have to just brush it off and start over.
