• Dedicate your life to something far greater than yourself
• Search for questions that compel you to keep going
• Science is one tool for social empowerment [/su_boxnote]

[dropcap]C[/dropcap]ognitive Scientist Daniel Dennett once said that “The secret of happiness is: Find something more important than you are and dedicate your life to it.” I would say that ever since I embarked on what is slowly unfolding as my story in science, I have hearkened back to that maxim, albeit with a minor edit. That “something” I am searching must be a question I feel especially equipped and suited to answer, since there is a plethora of important causes deserving of our time and energy. It appears to me that one of life’s struggles is learning to focus on your own path, while having faith that others will tackle the rest. As a matter of fact, that faith and collaboration is essential in practical science as well given the many mysteries in nature that still require us to unravel together.

I would say there are three main episodes that come to mind when I think of what distinct stages have led me to my present state. The first episode took place all the way in Japan, where I was spending my 10th grade spring break with my family. One night at dinner, our family friend who lives in Kyoto was telling us stories about his work as lead molecular geneticist at Kyoto University. He was describing one type of cells called the Induced Pluripotent Stem cells which were the next big thing at the time. He was sharing his excitement at conducting research in the field as well as the tangible impact it would have on society. It is crazy to think that this was the first time I consciously registered that being a scientist was an actual profession I could pursue. I remember being so awestruck by this possibility that I remained glued to his stories for the rest of the evening.

Of course, I quickly pledged myself to becoming a future molecular geneticist. I started reading more about the field and stumbled onto Nessa Carey’s book – The Epigenetics Revolution – which served as my first science book (little did I know 5 years later I would be working on a project centered on epigenetics). I remember being very fascinated by the human studies that were tracing various metabolic or neurological abnormalities to environmental factors. I thought to myself, what better way to delve into the perplexing, yet captivating “Nature vs Nurture” debate than to study epigenetics. I was unconvinced by statements such as “We are our brains”, because just intuitively speaking, I felt like we were so much more.

Another portal to understanding who we are is Alzheimer’s disease.  This is paradoxical, since Alzheimer’s erodes our sense of self by gradually stripping away our memory until we can no longer remember the most basic facts about our lives. I came to this realization the summer following my family’s trip to Japan when I did research in the Cognitive Neurology and Alzheimer’s Disease Centre (CNADC) at Northwestern University. I worked on a project investigating the molecular hallmarks of Alzheimer’s pathology in human brains. This experience marked the second episode that has led me to my present state: I was formally introduced to the field of neuroscience. During my time at the CNADC, I saw my first human brain and witnessed all the steps involved in preserving it — from autopsies to tissue mounting.

Concurrently, a close family friend had just been diagnosed with Alzheimer’s disease and I witnessed first-hand the overt behavioral changes arising from alterations in the brain’s organic matter. This experience accentuated the mysterious divide between morphology and behavior, as well as the more uneasy disconnect between the emotional labor involved in witnessing Alzheimer’s pathology, and the removed academic setting in which it is carefully studied. In an attempt to reconcile these opposing sides in my academic trajectory, I planned to double major in both philosophy and neuroscience in college. I believed that one needs both the introspective and objective measures to truly understand the human mind, and hence, the elusive self.

The questions we have that so deeply compel us to keep going only help us get back up after it feels like the whole world wants us to give up.

Throughout my studies, I was often told that neuroscience has two main mandates: studying nature and understanding disease. Upon first entering college, I was much more fascinated by the latter. Prominent scientists I had met and spoken to prompted me to start searching for my “question” i.e that “something” I would dedicate my life to. Convinced my questions would be found in pursuit of understanding memory formation and Alzheimer’s disease, I started working in a cutting edge Alzheimer’s and Depression research lab. The lab used novel techniques such as optogenetics to stimulate the Dentate Gyrus (DG) of the Hippocampus, a region of the brain implicated in the formation of new memories. A paper published shortly before I joined the lab had shown that stimulating the DG caused the retrieval of previously found to be lost memories in Alzheimer’s diseased mice — a discovery that dawned many exciting new interpretations of the disease pathology. 

The findings were riveting, and I gained first hand exposure to research in a field I felt viscerally moved by. I learned a lot from this lab; not only in the realm of key techniques used in neuroscience research such as immunohistochemistry, brain sectioning and genotyping, but also in the realm of instrumental soft skills required in conducting scientific research effectively. I experienced my “firsts” with pipettes, microscopes and mouse surgeries, and was more confused than ever before. I began to formulate my own questions with increasing sophistication, and learned how to approach forging a path to answering them.

The research path I was carving for myself was, however, tumultuous. Amid constant failure, I found myself foolishly comparing myself to those with far more experience than myself, and returned home many nights feeling defeated. Over the summer, where I worked full time in the lab for around two months, I came face to face with my deepest flaws. I questioned myself every day, wondering whether or not I was truly cut out for academic research in neuroscience. When everything else in the lab seemed to be running so smoothly, things weren’t working out as such in my hands. I faced a multitude of new obstacles that took me weeks to surmount. If it had not been for my friends and the little voice inside telling me to focus on why I had started research in the first place and to keep going, I would have almost certainly given up.

At the end of the summer, I felt grateful for the significant learning and growing I had done that had shaped my identity as a scientist. But ultimately, I wanted to keep exploring new research avenues and exposing myself to different lab environments. Instead of moving to another Alzheimer’s or cognitive neuroscience lab, I chose to dig deeper in an effort to unearth the more molecular mechanisms underlying human nature and evolution. I felt that delving into a completely new realm of research would only complement my future inquiry into disease.

I switched to a new lab and started working on a project studying Transgenerational Epigenetic Inheritance (TEI). Epigenetics literally means “above genes” and it describes how the environment impacts gene expression through so-called epigenetic markers. TEI refers to the transmission of these epigenetic markers from one generation to the next, so that the descendants of the individual who was initially exposed to that environment bear the scars of their ancestors. This hits home as my father was a refugee from Iran during the Revolution where he fled from the persecution of Bahá’ís. Stories such as these harbor sadness and trauma that could lead to cultural, but perhaps also physiological, imprints on future generations.

Serendipity reunited me with the question I was initially interested in: what makes us who we are? Eager to understand trends in historically oppressed communities and frustrated by the impasse I was feeling with how we were tackling the mental health epidemics, I was determined to understand how these susceptibilities arose. In doing so, I hope to work towards cultivating strength and resilience in individuals in an effort to help them escape the specters of crime and poverty. Pivoting from understanding disease to studying nature marks the third, and present day, episode of my story.

Bringing clarity to the complex phenomenon of TEI seems to preside in the distant future, as there is much to be unearthed when it comes to human development. However, the general principle that there are aspects of ourselves that lie out of our reach because of the unfortunate circumstances we or our ancestors have been exposed rings true. Heightening our consciousness thereof can only alleviate the burden many members of society, such as veterans or refugees, face. Further, these insights can shed light into how we can best navigate criminal justice proceedings or (re)integration into society. To me, the very real impact this research can have on people around the world illuminates both the power of basic science research and the merit of interdisciplinary approaches to real world problems. From a philosophical standpoint, this research weds our internal states with the external world, reconstructing the notion of the self as a fluid, unbounded entity — one with the world around it. As such, the most recent chapter of my story in science ended up feeling the most human.

Over the past year and into this upcoming summer, I will continue to hone my skills as an undergraduate researcher and absorb as much as I can about the academic research around me. I am seizing every opportunity that comes my way. I believe in the power of science to discover physical reality and gain insights into human conduct and the life of society. And I also trust in its faith to embolden individuals like myself to investigate the world around them fearlessly. Nothing about my journey so far has been smooth, nor providential. Rather, it has been characterized by hard work and personal faith. I am lucky to have supportive mentors today; however, there were far more voices telling me I was not qualified for large parts of my story. I therefore feel compelled to help others empower themselves through science and actualize their potential. In that regard, I find science is yet another tool for social empowerment, albeit one that should mainly come from within.

Today, whether through the UN IVY STEM Connect program, a project under the Girls Education Initiative, where I host weekly science workshops with young girls in Tanzania and Rwanda via Skype, or on campus through organizing panels and conferences, I strive to advocate for science in many forms. The main message I try to communicate hearkens back to advice Bianca, my postdoc mentor, gave me to me earlier this semester when I was doubting myself: you should never base your self-worth on science as it is a mystery for us to unfold and it does not care about you. This self-worth and confidence in your abilities must come from one’s own faculties, and the onus is therefore on each individual to reflect on what environment best conduces to strengthening those inner faculties. For me this meant switching labs, but that was an example of one decision out of the many I will still have to make to buttress my own journey.       

The bottom line is that before we can dedicate our lives to that “something” far greater than ourselves, we have to have faith in our own abilities to contribute to scientific advancements. The questions we have that so deeply compel us to keep going only help us get back up after it feels like the whole world wants us to give up.
