About me

Hi, I'm Samuel. I am a research fellow at Harvard in Prof. Prineha Narang's group, and a Ph.D. student at MIT (Massachusetts Institute of Technology) in Electrical Engineering and Computer Science. I am also a founding partner of my startup Assist-o, offering personal and professional assistants to business people and small companies. I currently spend most of my time in Cambridge, Massachusetts, but often travel around. My main areas of interest are Machine Learning and Quantum Computing, in which I have eight publications and one pending patent.


I am originally from Germany but spent almost all of my life in other countries (the US being my 9th). When I was 5 years old, my family moved to Croatia through a German NGO, to help with post-war reconstruction. There I finished elementary and high school. I also went to school in South Africa for a while, as an exchange student. After graduating from high school, I worked as a volunteer teacher in an orphanage in Kenya, near Nairobi, where I started a small coding  school program for disadvantaged children.

During my undergraduate studies, I worked in Ice & Climate research at the Niels Bohr Institute, at the University of Copenhagen in Denmark (see publications). Afterwards, I joined the hedge fund D. E. Shaw & Co. in London and New York City for a while, where I created computer simulations of the bond and foreign exchange market. Before starting my master's degree at EPFL, I spent some time in the sunny and picturesque city of La Jolla, at University of California in San Diego. There, I worked on Machine Learning research (see publications) and enjoyed surfing in the Pacific Ocean.


Since September 2018, I am studying Physics and Data Science at EPFL in Switzerland. As a research assistant, I work in the group of Prof. Giovanni De Micheli on Quantum Computing. I am also the founder and former president of the EPFL Quantum Computing Association and former vice-president of the Debate and Model United Nations association. In the Summer 2019, I worked at the National University of Singapore on Quantum Optimization Algorithms, with applications in finance.


Since February 2020, I work in Prof. Prineha Narang's group at Harvard on Near Term Quantum Algorithms for Optimization Problems. I am starting my Ph.D. in August 2020 at MIT!

SemiHD: Semi-Supervised Learning Using Hyperdimensional Computing

  • Conference: IEEE/ACM International Conference On Computer Aided Design (ICCAD)
  • M. Imani, S. Bosch, M. Javaheripi, B. Rouhani, X. Wu, F. Koushanfar, T. Š. Rosing
  • Research done at University of California, San Diego
  • Contribution: We developed a new semi-supervised Machine Learning algorithm. We noticed a significant increase in performance, as compared to state-of-the-art algorithms.
  • My contribution: I was responsible for coding the entire project, improving the mathematical algorithm and testing it against other state-of-the-art algorithms


AdaptHD: Adaptive Efficient Training for Brain-Inspired Hyperdimensional Computing

  • Conference: IEEE Biomedical Circuits and Systems (BioCAS)
  • M. Imani, J. Morris, S. Bosch, H. Shu, G. De Micheli, T. Š. Rosing
  • Research done at University of California, San Diego and EPFL, Lausanne
  • Contribution: Improvement to previous Hyperdimensional computing-based Machine Learning algorithms by introducing adaptive learning rates. We managed to significantly decrease the convergence time during training.
  • My contribution: I was the first person to introduce the concept of learning rates in HD computing and performed the initial tests with adaptive learning rates. My colleagues at UCSD developed the rest of the project and wrote the paper.


CompHD: Efficient Hyperdimensional Computing Using Model Compression

  • Conference: IEEE/ACM International Symposium on Low Power  Electronics and Design (ISLPED)
  • J. W. Morris, M. Imani, S. Bosch, B. L. Baxter, H. Shu, T. Š. Rosing
  • Research done at University of California, San Diego
  • Contribution: We invented an algorithm for ultra-low-power devices with limited memory to perform offline Machine Learning. It does so by compressing multiple vectors into just one vector by encrypting them with randomized vectors, and then decrypting them during inference.
  • My contribution: I was responsible for coding most of the project and improving the mathematics and statistics behind the algorithm. I invented an orthogonalization method, which significantly improved the classification accuracy by decreasing the influence of noise caused by the randomness.


Particle shape accounts for instrumental discrepancy in ice core dust size distributions

  • Journal: Climate of the Past / European Geosciences Union
  • M. F. Simonsen, L. Cremonesi, G. Baccolo, S. Bosch, B. Delmonte, T. Erhardt, H. A. Kjær, M. Potenza, A. Svensson, P. Vallelonga
  • Research done at the Niels Bohr Institute, University of Copenhagen
  • Contribution: Significant progress in measurement techniques for ice and climate science.
  • My contribution: I was the first person to have had a detailed look into the dust particle size distribution from ice cores from the North Pole. I found out that laser measurement techniques used for the past 20 years have been very inaccurate. My colleagues theoretically and experimentally confirmed this and wrote the paper on it.
