  • Scott Strang
    Scott Strang Senior Project Leader

    Innovation strategy, organizational transformations, robot boats and getting dogs to point at things on a competitive level — is there anything Scott can’t do?

    A man of many talents, Scott uses his extensive knowledge and understanding of consumer demand to hunt through the weeds and flush out solutions for his clients every day. Then, every night, he goes home and teaches his dogs to do the same thing.

    As someone who once spent time in an MIT lab researching and designing an autonomous kayak, it may come as little surprise that he is also a natural when it comes to shining a light on R&D insights.

    Scott also uses his diverse set of abilities to aid clients with innovation strategy, organizational transformation and finance design.

    But can he climb a mountain? Of course, he can. After viewing the mountains while hiking through Yosemite, Yellowstone, the Dolomites, Alps and Glacier National Park, he figured the next logical step was to climb them. So, he did.

    It doesn’t matter if you need a business problem solved or a boat that will row itself across the lake to teach a dog to climb a mountain, Scott brings his knowledge and passion to every project he encounters.

  • Aaron Zarenczanski
    Aaron Zarenczanski Project Leader

    Aaron comes to us by way of New Mexico, Brazil, Saipan and Neverland.

    As a child, the movie Hook ignited a passion in him for TV and movies. His interest quickly grew beyond the Peter Pan tale to include international films including the Italian film 8 ½ which we hadn’t heard of either.

    Aaron chased the dream to Hollywood by pursuing a career in the industry where he became a producer and executive of development and strategy with a production company working on such titles as Return of the Living Dead.

    But one day, he started to missed the structure of the professional world and he realized that he had to leave Rufio and the other Lost Boys behind and follow his other passion. So, along with degrees from Insper in Sao Paulo and UCLA, he has brought his cinematic creativity to SSG.

    Aaron also enjoys rock climbing, snowboarding and sleeping under the stars.

    Just like a true Lost Boy.


  • Sara Ding
    Sara Ding Project Leader

    Hailing from Beijing & Changsha, Sara has constantly fed her craving for knowledge. This had given her both a breadth of knowledge and a fondness for Batman. Much like her favorite super hero, Sara is always looking to improve knowledge and physical skills.

    In between her time at USC and her graduate studies she served several internships to optimize her learning and indulge her curiosity. This experience led her to choose the management science and engineering program at Stanford combining quantitative analysis, technical skills and qualitative insights.

    She’s passionate about problem solving and loves applying her skills to provide clients with solutions. Her other passions include running and performing on the stage as well as volunteer work with the homeless and children.

    Cristina joins us from the beaches of California by way of the State Department. She holds a Masters in City Planning from MIT, an MA in conflict resolution from Georgetown, and a BA in international affairs from George Washington. If you find yourself in a heated argument about which train you’re supposed to take in London, she’s the one you want around.

    Cristina’s time at the State Department involved processing Freedom of Information requests and generally safeguarding our liberties so we’re pretty sure she can keep a secret. Her talents include Statistical Analysis, Data Visualization, petting cats and throwing ceramics. She is not a fan of throwing cats or petting ceramics and she wanted us to make sure we got that last bit right.

    In addition to creative problem solving and a desire to help her clients, Cristina brings a passion for street food, Old Fashioneds, and the Northern California ocean.

    So if you’re looking for where to get the best baked potato with a cup of vin chaud in Paris, the freshest sautéed noodles with smoked pork and chili sauce in Singapore or the tastiest Old Fashioned in Boston, Cristina is the one to talk to.

  • Phoebe Jiang
    Phoebe Jiang Associate Project Leader

    With a passion for ancient civilizations and an affinity for modern science, Phoebe swears to us she won’t use her knowledge to build a time machine. While we realize that’s exactly what someone who was building a time would say, we are thankful she brought her skills to Sharma.

    Phoebe’s desire to become a scientist and healthcare worker brought her from her home in Guangzhou to the US where she studied Molecular, Cell and Developmental Biology, Neurobiology and Anatomy. During her studies she researched Alzheimer’s disease, Parkinson’s disease and totally not how to build a time machine to visit Ancient Egypt she swears.

    Phoebe soon fell in love with consulting when she was introduced to case practicing at Northwestern University while pursuing her Masters. After that, she never looked back. We’re excited to have her here at Sharma where her skills in business process improvement, data analytics, opportunity assessment and more can be put to use serving our clients and not threatening the space time continuum.

  • Pallavi Geethika
    Pallavi Geethika Senior Associate

    Despite Destiny’s Childs’ mother, Destiny’s, advice, Pallavi loves hiking in search of waterfalls. One of her current goals is to visit all 63 major National Parks in the near future. This means that she’s always looking for a ride to the next one on her list.

    Pallavi loves a good road trip and makes a great passenger. She can carry on a conversation in 6 languages, sing classical Indian songs or play the movie quote game for miles on end.

    She earned her Economics degree from the University of Chicago and still resides in the city. When she’s not out shirking Beyonce’s words of wisdom, she’s sticking to the rivers and the lakes that she’s used to. She spends her time exploring Chicago and cataloguing the best coffee shops, restaurants, bookshops and live music venues the city has to offer.

  • Jessica Cheng
    Jessica Cheng Senior Associate

    Economist. Consultant. Chameleon? Jessica Cheng has always been adaptable.

    Before Covid, you could find her enjoying the view from the top of a mountain or crossing streams while hiking through nature. She enjoyed jet skiing in Mexico or praying at a temple in Japan while travelling the world. But when Covid changed everything, she quickly pivoted and took her hobbies indoors.

    She traded Mountain climbing and hiking through rivers for baking bread. She scaled the greats like Mt. Sourdough and Ciabatta Peak. She traded Jet Skiing in Mexico and praying at temples in Japan for coffee tasting and found thrills and relaxation in caffeine’s warm embrace. And she traded traveling the world for not traveling the world—just like everyone else.

    This extraordinary flexibility is just one of the many skills Jessica brings to her work at Sharma. With her degree in economics from the University of Chicago, a CAMP certification and years of experience, Jessica is ready to put her passion to work for our clients.

  • Sergio Castillo
    Sergio Castillo Senior Associate

    Man of action. Volunteer. Chesapeake Bay Retriever wrangler. Sergio’s winding path to SSG includes time in the OR and more than a few ambulance rides.

    With his eyes set on working at the UN, Sergio began his education in political science and business administration. But, once he began working as an EMT, he turned his focus to emergency medicine and studied neurobiology, biochemistry, virology at the University of Pennsylvania. He even spent time in the OR assisting an oculoplastic surgeon.

    Soon after he took his passion for business to Duke’s Fuqua School of Business where he double majored in Management Studies and “Science, Technology, engineering and Mathematics.”

    All of this means that Sergio knows how the consumer mind works. And, if it’s not working, he can peek inside and see why.

  • Defne Talu
    Defne Talu Senior Associate

    Armed with a degree from the University of Chicago, Defne has hunted terrorists, is handy with a sword, and recently started weightlifting. That is why we ask that nobody make any sudden moves.

    Defne’s past takes her from Turkey and New York to fencing state champion and beyond. Along the way she’s learned four languages, developed a passion for baking, and played three years of professional volleyball. She has used her skills to aid banks, consulting groups, and even did some instructing of her own while at the University of Chicago. This includes working with the World Bank on how to apply economic tools to the fight against terrorism.

    With a toolbox that includes an expertise in épées, a flair for finance and a simply wicked serve, Defne is a welcome asset to the Sharma team and one that we are all extra especially nice to—just in case.


  • Shannon Kollasch
    Shannon Kollasch Associate

    You might find Shannon dancing in a ballroom, playing violin in Chicago’s Chinatown, or hard at work at a non-profit to decrease educational inequality. Her energy is endless. Is this some weird mad science type side effect from her time at Northwestern University where she was working on sustainable energy? Probably.

    This new secret form of energy has helped her in her passion for growing organizations and helping them operate better. In college she grew her cooking class from 10 to 250, developed mentorship avenues in her materials science club, all while testing new methods for creating high-performance solid oxide fuel cells and watching parakeet videos.

    Shannon brings that same boundless energy to her work at Sharma helping clients solve problems, optimize processes, grow their business, or work on their salsa.

    As long as she uses her powers for good, her secret is safe with us.

    COLE DADY Associate

    Reggaeton is a musical style that combines Reggae en Español, Hip Hop, Dancehall, Bomba and Plenta. And, not only is Cole Dady a fan of the music, he also embodies this eclectic mix of styles.

    While he was at Boston College, he mixed a no-spin approach to journalism as the Editor of the News section for the school paper with a very spinny turn on the school’s swing dance team. He
    then attended both HEC Paris and MIT Sloan in a dual degree program in which he earned a Master in Management from HEC Paris and a Master of Finance from MIT.

    He interned as a financial analyst, investment banker and private equity analyst while also volunteering with Chance for Children, a non-profit providing adoption services, education programs, community development and more for children in Haiti.

    In short, Cole is a straight-shooting, finance analyzing, swing dancing, kindhearted, children helping, Master of Finance that loves listening to Reggaeton. And we’re happy to have him at SSG.

    IDAN KATZ Associate

    From the frozen plains of the Antarctic to the boardrooms of the world, Idan is always up for a new adventure.

    As a scuba diver, he’s equally comfortable diving into the open sea or an ocean of data to discover the secrets they hold. As a wildlife photographer, he’s able to capture a snapshot of gorillas in Rwanda or an insight from an assignment and use it to enlighten the world. And, as a soccer fan, he’s really good at kicking things.

    His time at Northwestern and career experiences have taken him around the world from Tel Aviv to Prague. He’s worked in Israel, Cyprus and the USA. And, where work didn’t take him, he went in search of adventure. He’s set foot on all seven continents, many different countries, and can’t wait to see the rest of the world.

    Idan has studied economics, business and integrated marketing communications and can’t wait to put his skills to work on the next project. On to adventure!

  • EVA LI
    EVA LI Associate

    She could sweep you off your feet, cook you up a delicious Tomato Braised Beef or pull innovations from insights. Just don’t mess with her hamster.

    Eva has been studying dance from when she was young all the way through her time at UCLA. She’s a student of traditional Chinese dance, Hip Hop and often does K Pop covers with her friends. You can see this nimble nature in her work as she moves effortlessly from one project to the next.

    The attention to detail she shows in her work can also be seen in her passion for portrait photography. This is a hobby she’s had for years, often using her identical twin sister as a subject. She denies that this is just a selfie with extra steps. But it is.

    Eva can teach you to dance, take your portrait, or provide creative solutions for your business problem. All you have to do is ask. Just watch out for her hamster that she describes as “cute but fierce.” It might be trained. You’ve been warned.

  • Sophie Lyu
    Sophie Lyu Associate

    From Übermensch to Uber the ride sharing platform, Sophie’s has had a few interesting stops along the way to SSG. Before getting her Master of Science in Analytics, Sophie majored in Mathematics and Philosophy, where she wrote her honor thesis on Nietzsche.

    While pursuing her masters at the University of Chicago, she interned with Uber and helped determine the product development pace of the company’s first mobility pilot with autonomous vehicles. This put autonomous vehicles on Uber’s platform for the first time.

    Now she has turned her considerable powers of analysis to helping clients. In addition to analyzing data and creating solutions, she continues to question whether truth is simply the name given to the point of view of the people who have the power to enforce it, studies classical guitar and enjoys trying new and delicious foods.

  • Giselle Wang
    Giselle Wang Associate

    Giselle has practically spent her life turning science fiction into science fact. Maybe it began with a love of Asimov or Phillip K *** novels. But, instead of asking if Androids Dream of Electric Sheep, she wondered if the secret to defeating cancer was locked inside whale DNA.

    Because marine biology and harnessing the building blocks of life to find an innovative genetic cure of hypoxia for human patients with strokes, cardiovascular disorders, and cancer isn’t enough, she’s also a rock star. She is the lead singer/guitarist for her synth wave band and produces tracks that would feel right at home in the world of Blade Runner.

    So, what do you do next if you’re a roller skating, sci-fi loving, monofin diving, genome sequencing, whale studying, cancer fighting, rock star with a double major in marine biology and economics? You use everything you’ve learn to help make the world a better place by helping businesses develop more efficient and sustainable practices. Because this is the only planet we’ve got…for now.

  • Alex Sharma
    Alex Sharma Social Director

    A social butterfly from Day 1, Alex has always had the ability to put people at ease and make them smile. And, even though Grandmas are his favorite, he has a smile for everyone.

    A foodie at heart, he loves strawberries and refuses to eat salmon unless it is accompanied with curry as nature intended. A frequent flier, Alex has traveled extensively and already dined at a Michelin starred restaurant. About the only thing he loves more than his food, is a ride in the great outdoors in the Baby Bjorn with Vish.
