Aim Photonics is my first internship where I do real research; I was surprised of the abilities and qualities that someone needs to have in order to explore new fields and discover new ways to make life easier by building new devices. I believe that is very difficult to do research because the people who are doing research are working in something that nobody worked before. Sometimes there are not a lot of reference or papers similar to what they are doing; therefore, there is a lot of fails every day in the labs. I am having a very good time working in my research cleaning and preparing silicon surfaces to grow III-V epitaxy with my mentor Dan Pennachio; I am learning a lot from him because he always helps me and explains things in a way that I can understand. Also, all the members of the Palmstrom’s group helps me by giving their opinion about my research and suggest me things to do to improve results. Palmstrom’s lab is super interesting because is hard to believe that such technology can exist. I am performing several methods to clean the surface of the silicon and I am using several equipment to analyze how good the procedure is. Using these devices makes me to feel lucky because I am using apparatus of millions of dollars that not everybody can have the opportunity to use. Also, all members of the Palmstrom’s group motivated me to continue my education and I started to think that maybe I would like to become a research scientist.
- Play music
- Listen to some of your favorite music. Or, try some new genres or styles. You have plenty of time and varying the sound will keep things more lively. Personally, I like to listen to mostly classical and big band jazz, but I do throw in some 80s rock every now and then. With all these streaming sites, you have access to an incredible library. Spotify and Pandora provide free access (with commercials) to all sorts of music and will allow you to explore a plethora of artists of the same or similar genres. YouTube has everything from amateur covers to playlists of your favorite albums. SoundCloud can help you discover up and coming artists or smaller non-mainstream artists. If you’re into classical music as I am, UCSB has a subscription to the Naxos music library (http://www.library.ucsb.edu/research/db/250), which has over 140,000 tracks of mostly the classical genre, but does have some jazz, world, new age, and pop and rock.
- Listen to an audio book
- Reading simply isn’t possible in an optics lab. It’s dark and you’re busy using your hands and eyes to take measurements. There’s a few free ways to get your ears on an audiobook. LibriVox offers free volunteer read books in the public domain. Audible, by Amazon, offers a free 30-day trial period, but after that it’s $15/month. Audiobooks.com offers 1 free audiobook after joining. I haven’t tried using audiobooks much, but my friend, who was performing AFM measurements for several weeks, found himself going through a multiple books per week!
- Take sun breaks
- In addition to taking a lunch break (don’t skip lunch!), you might find it helpful, relaxing, and invigorating to take 10 minutes or so and take a walk outside. Find a patch of grass, lie down and watch the clouds glide by. The lab I work at is a mere 3 minute walk to the beach, so that’s always a nice option. Perching on the bluffs, watching and listening to the waves roll up to shore. Being in a dark room for extended periods of time can get lonely, disorienting, and cold. Taking a break to go outside, breathing in some fresh air, feeling the grass beneath your feet or the sand between your toes, maintains your sanity in the dark bleakness of a light sensitive lab.
- Have a partner
- If possible, having a lab partner makes the experience much greater. You can talk, share music interests, alternate turns taking the monotonous data, which brightens up the dark room. In my lab, I’m lucky enough to have a partner. We have similar music interests: he appreciates classical, enjoys jazz, but also has a wider palette of genres than I, which brings some variety to the table. We talk about tv shows, science, career plans, social lives, politics and whatever comes to mind. We grab lunch together and enjoy the trip outside to lunch. Having a partner will delay the onset of insanity, but not eliminate it, be sure to still get out of lab some time.
What might an undergraduate intern do on a day-to-day basis? Well, it certainly differs by field, and differs still by individual lab and project–so here’s a look at what I do as a mechanical engineer working in Sumita Pennathur’s lab separating particles using microfluidics.
Some activities that I find myself doing often are:
- making solutions
- use syringe pumps
- taking long exposure images
- analyzing images with Matlab
Making a Solution (How to Use an Eppendorf Pipette)
- Set the pipette to the correct volume, attach pipette tip.
- Depress the top button to about halfway, insert pipette into substance.
- Release the button and take it out of substance.
- Insert pipette into desired location and depress the button all the way down.
- Discard the pipette tip in a waste bin and shake up your solution.
How to Use Syringe Pumps
- Insert infuse syringe and refill syringe
- Set diameter of syringe (26.7 mm)
- Set infuse rate (mL/hr)
- Set refill rate (mL/hr)
- Press run
Taking Long Exposure Images (How to Use Andor Solis)
- Using bright field, position your subject in the desired location relative to the camera
- Make sure that the camera is focused
- In the “Setup Acquisition” menu “Setup Camera” tab, change exposure time and number of accumulations (Example: In the “Setup Acquisition” menu “Auto-Save” tab set your file stem and save location
- Click “Video” to see your subject in real time
- Click “Take Signal” to capture the image
Analyzing Images with Matlab
- Have your images organized and labeled well
- Create code to run through each image (for loops)
- Create code to extract the data you want (in my case, equilibrium distances)
- Plot your data
- Understand that you will experience errors
This has been a journey through a day in my lab. Note that labs differ greatly. Although you probably won’t use syringe pumps or Andor Solis, it’s likely that at some point in your lab career you will make solutions and do some form of programming to analyze your data. Regardless, you will learn a lot of new skills in lab that you might not learn in class.
Before this internship, I honestly had no idea what research meant. The idea of being a researcher didn’t seem exciting. I am the type of person that likes to be hands on. Whether I am working on a project or even studying. Hands on studying to me is achieved by getting up and using whiteboards and organizing study groups. This is one of the reasons I believed that I wasn’t the right type of person to fit into the research field. Thankfully, my mind has opened up to the idea. My perspective on my future has changed in positive and exciting ways.
Research is much more team oriented than I expected. My colleagues and I tend to have similar questions as we use and learn very similar simulation programs to carry out our experiments. In most cases, it isn’t ideal to ask the mentors questions for every minor road block. This is when our small office conversations allowed us to learn from each other. A majority of the time, the learning was reciprocal. Progress achieved independently is so rewarding.
Cutting edge technology comes from universities with these programs. I didn’t know this was true. I believed it was all industry that was responsible for this. This internship has given me a new found inspiration to pursue research. I will pursue a undergraduate research program in hydrogen technology thanks this experience at my new school because of this internship.
Wow! As this summer program comes to an end, I am exhausted…
Not the overwhelmingly sleep-deprived exhaustion. But instead, the kind of exhaustion that shows that you have accomplished something—like being out of breath after running.
At the end of a run, you know that you have earned not only the tiredness and soreness, but also the strength that ensues. So as I gear up to sprint the last couple of weeks of the MARC summer program, I know that I will be even more exhausted than I am now. But I also know that there is a great reward waiting for me on the other side of the finish line. I have struggled in workshops to improve my writing and presenting and labored in lab to develop my technique and skills. But there is satisfaction in knowing that you have challenged yourself, struggling through new obstacles and emerging stronger and wiser than before. There is fulfillment that comes with presenting work that you have invested time in and believe in. And there is gratification that comes with knowing you have worked on research that has helped not only your growth, but could also potentially benefit many others.
However, as I run my course, I am not alone. I have met second years that hold so much promise, my fellow third years that have offered encouragement as we run similar courses, and fourth years that are looking ahead to bright futures. As we run along side one another, my peers have seen me struggle when my stride faltered but have only given me positive support to continue. They have provided me with laughs to distract from my labored breathing telling me to slow. To sum it up, they have been pretty awesome!
So if you are looking at the CSEP programs and wondering if all the hard work is worth it… it is. The opportunities that these programs give you are so unique, and only a small group of undergrads gets to experience them each year. From workshops on conferences and graduate school to dinners with experienced scientists from academia and industry, there is always something new to learn, and there is always someone new to meet. So, if you are like me, you may be exhausted, but the soreness just means that you are getting stronger.
