Who am I?

I am an enthusiastic and creative thinker with 15 years of experience in academic and scientific research, technical projects, diplomacy, community service, and education at all levels. I have worked at institutions around the globe with people coming from a diverse array of backgrounds. I strive to improve the welfare of every individual and our global community while empowering others to do likewise.

Science Diplomat

A safer and sustainable future with science

I find immense satisfaction collaborating with the international community to chart a path to a more sustainable future with science and technology. As a science advisor in the Department of State, I support initiatives that leverage the peaceful uses of nuclear science and technology to support the sustainable development while working towards a world free of nuclear weapons. This includes supporting multilateral organizations like the International Atomic Energy Agency and implementing new programs like the Sustained Dialogue on Peaceful Uses to accelerate progress on the UN Sustainable Development Goals.

Thinker and Technical Handyman

Problem solving and big data

I enjoy asking questions that challenge myself and others, bringing definition to ill-posed problems, and finding solutions. I pursued a PhD in particle physics out of an intrinsic curiosity to understand the fundamental laws of nature. Since that time, I have developed the ability to manipulate and tease out meaning from big data sets, to construct and operate high speed electronics, and draw insights into the natural world. My mantra is "learn, discover, be excited!" and I relish every opportunity to share this excitement with others.

People Person

Dynamic leader and mentor

As a member of one of the 3000-person ATLAS collaboration, I have cultivated a set of "soft skills" that enable me to better serve others. Particle physics is an international endeavor with a global community, is both cooperative and competitive, and inherently relies on individuals learning (and teaching) while pursuing their own research. I know how to prioritize my work to pursue multiple projects in parallel while guiding teams to succeed. I strive to catalyze communication within a team and I prioritize mentor others to cultivate talent - the stronger your teammates become, the stronger your team becomes.

My Journey

This is an abbreviated list of my formal education and professional path. In many cases it highlights only superficial details (i.e. where, when, what ...) and as formative as academic and work experience can be, and for me has been, I feel its important to always remember that much more than what can go on paper makes an individual.

Mark Twain

"I have never let my schooling interfere with my education."

What do I do?

My curiosity led me to pursue physics and it has perpetually boggled my mind that we can begin to comprehend the natural world (... let alone anything). At the same time, I hold the belief that without caring for the welfare of others, many efforts are done in vain. As such, I have intrinsically been drawn to activities and initiatives involving other people. This ultimately led me to the realm of multilateral diplomacy as a science advisor.

Diplomacy

Building a sustainable future with science

The challenges that face the world are immense - climate change, famine, nuclear security. I am a firm believer that (1) international cooperation is essential to address these, (2) science provides humanity with critical insights and tools for change, (3) governments must work for the people and play an indispensable role in designing and facilitating solutions. As a science advisor with experience facilitating technical collaborations, I design and implement foreign affairs policy in the U.S. government at the nexus of nuclear nonproliferation and sustainable development with the peaceful uses of nuclear science and technology.

This initiative is designed to provide a forum to engage scientists, governments, the development community and private industry in non-binding and voluntary dialogue to more fully explore the ways in which the peaceful uses of nuclear science and technology can contribute to the UN's 2030 Agenda for Sustainable Development.


Science

Searching for a frictionless vacuum

A fascination with the extremes of nature, a desire to deconstruct and understand "the thing that that other thing is made of", and an appreciation for the abstract beauty of creative thought - these were the most valuable lessons that Mr. Dumoulin showed me in high school science. I set off to university to become a medical doctor, but ended up a philosophical doctor practicing experimental particle physics at the CERN laboratory in Geneva, Switzerland. [Spoiler Alert : the vacuum is anything but a vacuum.]

Great Scott!

ATLAS Experimental Collaboration @ CERN

2008-Present

Dark Matter and New Physics

I search for new particles and forces (e.g. dark matter) not currently described in the paradigm of particle physics by studying the data collected by the experiment. This requires translating physical intuition and an appreciation for the abilities (and limitations) of a physical detector into performant computer programs. These programs are integrated with the millions of lines of code within the collaboration’s analysis framework, and used to process large datasets using a grid of cloud computing resources distributed around the world.

Automated Computing

I work to automate the data analysis that we do by developing declarative, pipelined workflows. This not only allows for the same code to be used multiple times in the context of physics searches to make new and interesting statements about hypothetical scenarios, but can also take the busy work out of standard (but complex!) detector calibration procedures. This improves efficiency of analysis turnaround and frees up the time of others in the collaboration to think more creatively.

Hadronic Jets

I spend a considerable amount of time thinking about “hadronic jets”, which are collimated sprays of dozens of particles. The way these particles orient themselves with respect to each other, their “topology”, can tell you a lot about the type of particle from which they originated at the collision point in a bubble whose radius is about one femtometer (one one thousandth of a millionth the width of a human hair). Understanding their behavior requires not only physical intuition and programming but often times the use of machine learning. I specialize in understanding jets coming from W bosons and top quarks as well as those originating from the Higgs boson

Leadership and Management

My talents and ability to perform good research while helping others succeed has been recognized multiple times within the collaboration. I have been elected multiple times to lead groups ranging from a few students to upwards of a hundred collaborators on topics including (i) dark matter searches, (ii) hadronic jet tagging team, and (iii) Higgs boson tagging.

FASER Experimental Collaboration @ CERN

2019-Present

Ultra Long-lived Particles

Perform searches for ultra-long-lived particles produced in proton proton collisions at the LHC in a region of the accelerator that is left uncovered by the ATLAS experiment - down the beamline.

Electronics and Data Acquisition

I am one of the core designers and developers of the faser/daq data acquisition system, specifically the portion responsible for reading out the trigger and timing scintillators and the calorimeter signals. It is this detector readout that bears the sole responsibility of identifying interesting signals for which the data from the entire suite of detectors will be recorded.

Large Area Picosecond Timing Detectors

2009

Faster Detectors

Novel development of detectors is critical to furthering particle physics and creating technologies that can be transferred to have a broader impact in society (e.g. medical applications). Timing resolution (i.e. how accurately a detector can identify *when* something occurs) is one of these improvements. Typical detectors have an accuracy of of a nanosecond (a thousandth of a millionth of a second). In this project, we wanted to do a factor of one thousand better.

Microchip Design

Early in my graduate career, I contributed to the design of first generation ASIC for front-end of large-area photo detectors with picosecond timing resolution by designing the low level circuitry for the readout microchip of the detector.

Sleeping Worms

2009-2010

Sleep Science

Although there are hypotheses, no one really knows why we sleep. However, we can study behavior analogous to the state of sleep in simple organisms, primarily the C. elegans nematode. This organism’s nervous system has about 1000 neurons and is remarkably identical from specimen to specimen. [david byron lab chicago]

Surgical Lasers

I designed and constructed a pulsed laser system to perform non-invasive dissection of the C. elegans nematode nervous system. The worms were not killed and with the system you can manipulate a specific part of their nervous system and see what happens (e.g. Does it still sleep?).


Education and Engagement

Lightbulbs ... and more lightbulbs

Learning is amazing, but to me teaching is beautiful. To me, it lives on the boundary of science and art - crafting universal knowledge in a uniquely personal way so that it can be internalized by another. And then the moment they get it, the lightbulb turns on, and the lamppost of humanity grows a little brighter.

Thru Hiking

Long walks, in the woods

Long walks - mountains, sunshine on your face, rain, cold, the smell of pine, sleeping outside, hot coffee while the birds chirp, a simple "Hey, how's it?" to a fellow hiker - place me in an unparalleled state of awe. This awe inspires in me a zeal for life and humility to protect the beautiful world around us with intention. Among the day hikes and weekend trips, I am fortunate to have had the support to have completed a number of long trails in Europe and the United States, including the Appalachian Trail in 2022.

A walk in the woods

Appalachian Trail (AT)

February - June 2022

2196 miles / 146 days (14 rest days)

While waiting for my security clearance at the Department of State, I walked the Appalachian Trail in spring of 2022. I began quite early on February 1 in Georgia and walked the classic route to Mt. Kathadin in Maine. My trail name was "Backstroke" until I nearly lost my left eye from a hawk attack in Maine at which point I was suggested to change it to "Hawkeye" (I didn't). Most days were spent walking by myself and contemplating my place in society and the world. Through this experience, I cultivated a whole new depth of appreciation for the simple things in life (a roof over your head and a hot meal) and the value of companionship. While not a traditional "professional experience", I grew a whole new sense of resilience that I now bring to each new venture.

Northville Placid Trail (NPT)

October 2021

135 miles / 8 days

The NPT is a low-key flat thru-hike in the Adirondack Mountains in New York. I did it a bit late in the year in October and the trail was either completely flooded from beaver activity or covered in leaves. It was a refreshing punctuation to my autumn and a way to discover the mountains that had been in my backyard as a child.

The Long Trail (LT)

June - July 2021

273 miles / 21 days

Upon moving back to the United States from CERN, I was living with my brother in Vermont and embarked on the LT as a way to discover the state. As the "original national scenic trail" that inspired the Appalachian Trail, the LT is an iconic fixture in the hiking community. With the first half paralleling the AT and the second half evolving into ever more rugged wilderness this was the first test of true backpacking and a mightily humbling experience for someone who thought themselves experienced in hiking.

Tour de Mont Blanc (TMB)

August 2020

270 km / 14 days

In the midst of COVID-19 pandemic, I embarked upon the TMB with a hiking partner and friend from CERN to circumnavigate the Mont Blanc massif and experience the hiking and "refuge" (mountain huts) community in Switzerland, France, and Italy.

Camino de Santiago (Portuguese)

June 2010

260 km / 10 days

During graduate school, I spent two weeks one summer hiking the Porto to Santiago camino as a pilgrimage. This was long before I considered myself a "hiker" and unbeknownst to me planted that seed that was to grow.

Martin Luther King Jr.

"Life’s most persistent and urgent question is: What are you doing for others?"

Sam I Am

(aka hobbies, interests, thoughts ...)

I consider myself a hiker, a runner, a reader, a chef ... the qualities that come with these hobbies are normal, some may be intense or idiosyncratic to others, but all are what make me the "Sam" I am.



Only pictures? ... no

Running

My Perspective

Running is how I meditate actively to preserve my own inner balance on a day to day basis. Whether a quick 5k after work or a marathon 50k daylong haul, every run provides an opportunity for an insight into life. And though getting to the end is not always pretty (or possible) getting out there is always worth it, even for a beer mile.

Mountains

My Perspective

Whether it is the Adirondacks in northern New York in the winter, hiking across Table Mountain in South Africa, or hiking from refuge to refuge through the Alps mountains inspire me with their power and ability to serve as a sanctuary to (safely) lose oneself. When possible, I treasure the ability to get into the mountains.

Investment in Africa

My Perspective

Africa is home to the fastest growing population and will be home to a majority of the world’s youth within our lifetime. The myriad of 21st century challenges necessitates a rapid increase in the standard of living throughout the African continent in a sustainable way. This is an intentional focal point of my professional life and enriches my entire life in many ways.

Community Building

My Perspective

I believe that local communities and face-to-face interactions (i.e. neighbors) serve as an integral part of society. And for communities to be successful, they must be cultivated. I enjoy that this can happen while doing something constructive (e.g. hauling firewood) that helps in a focused and pragmatic way. Though I also appreciate, and let’s face it I often prefer, when this happens over a pint of beer or by sharing a meal and breaking bread together.

Organizing and Planning

My Perspective

Chicken or the egg - which came first? I don’t know if my perverse enjoyment of organizing events and trips for groups with google docs came before or after I learned to organize for my research, but its a fun idiosyncracy that helps me make the most of any given trip with friends. So I’ll take it!


Henry David Thoreau

"I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived."
