My mission is to use creative problem solving to come up with clever, unique solutions for some of the toughest problems, and then test them using strong scientific methods. This means that on a daily basis, I must design and implement experiments; deal with large, complex, messy, multidimensional data sets; and present, persuade and instruct. I work closely with executives, senior engineering and product managers to help stop fraud at AppNexus.
Additionally, I am fluent in French.
Data Scientist, Signals Intelligence @ I am researching fraud on the AppNexus platform as a member of our new Signals Intelligence Group. My responsibility is to prototype, validate and experiment with systems to stop advertising fraud and malicious activity on the AppNexus platform. It's a big, fascinating problem! My prototypes and research are used by C-level executives and product managers at AppNexus. I am also working very hard on vetting external partners and vendors for their fraud data sets and solutions.
I am working on internet and computer security problems, using the following tools and packages:
- Spark, Spark Streaming and Kafka to process streams with over 1.5 MM records / second. I triage, cluster, classify and learn from AppNexus's enormous data sets.
- Forensic computing packages: VirtualBox, Wireshark, iptables, tcpdump and other unix hacking tools
- Pig, Hive, Parquet and the rest of the Hadoop ecosystem
- Python, R, Pandas, other scientific computing packages
- Postgres, MySQL for very large data sets From July 2014 to Present (1 year 6 months) Greater New York City AreaClient Insights Analyst @ Using rigorous scientific methods (i.e. controlled hypothesis testing based on evidence) and advanced scientific computing tools like Apache Pig, Hive, Hadoop, Python, Pandas, R, Vertica, etc., I conduct research and investigations into clients' Real Time Bidding campaigns on the AppNexus platform. Collecting data, developing models and communicating actionable strategies and changes to clients are my responsibility. Typically I assist our clients' product managers and CTOs with solving their Advertising Technology related problems in a scientific manner. In order to do this, I have to know the AppNexus platform backwards and forwards, requiring deep understanding of our platform and the theory of AdTech in general. From October 2012 to June 2014 (1 year 9 months) Greater New York City AreaMSc Student, McGill Departmenty of Anatomy and Cell Biology and School of Computer Science @ I worked on two problems as part of my Master's research. I developed computational model for the regulation of the expression of the prion protein gene expression in neurons afflicted with endoplasmic reticulum stress. Secondly, using a network model represented as a system of ordinary differential equations implemented in FORTRAN, I investigated the properties of protein networks in Breast Cancer Carcinomas. I conducted experiments on the nature and requirements of training data requirements for gradient descent algorithms to identify the properties of a network of cell cycle control proteins and inhibitor drugs. From June 2010 to October 2012 (2 years 5 months) Montreal, Canada AreaMSc Student, Lady Davis Institute @ Studied the mechanisms of Endoplasmic Reticulum stress mediated Prion upregulation in human neurons, using bioinformatics techniques. Responsible for experimental design, result processing (in Python and R), and conducting experiments in the lab. Primarily I worked with PCR, qPCR, Western Blots, Cell Culture and Luciferase assays. From June 2010 to October 2012 (2 years 5 months) Undergraduate Researcher @ - Researched the effects of Prion diseases (i.e. mad cow disease or Creutzfeldt-Jakob Disease) on the ability of human cells to undergo programmed cell death.
- Researched the interaction of the kinase CDK5 and the Prion protein using radioactive tracers. From May 2008 to June 2010 (2 years 2 months) IT Consultant @ Worked with three clients on highly specialized custom projects.
- Reverse engineered proprietary accounting software to build a custom reporting and forecasting database system for a medium sized business.
- Reverse engineered a obsolete and proprietary patient information system for a medical practice that needed to upgrade to modern software.
- Secured Linux servers that had been compromised, repaired and upgraded Asterisk VoIP installation. From 2006 to June 2010 (4 years) Montreal, Canada AreaEnglish Instructor @ Responsible for providing custom tailored English consulting and instruction to small businesses in the Paris metropolitan area. From February 2009 to July 2009 (6 months) Paris Area, FranceEnglish Language Assistant @ Developed English curriculum and lesson plans for 6-12 year-old students in the Paris public school system. From October 2008 to July 2009 (10 months) Paris Area, France
Master of Science (M.Sc.), Cell Biology and Computer Science @ McGill University From 2010 to 2012 BSc, Biology @ McGill University From 2005 to 2010 High School @ Inter Lakes High School From 2001 to 2005 Michael Misiewicz is skilled in: Apache Spark, Spark Streaming, Python, Tcpdump, Iptables, TCP/IP, Linux, Database Administration, Molecular Biology, R, Databases, Data Analysis, Cell Culture, Statistics, Network Administration
