📖 Summary

I am currently participating in the Insight Data Science Fellowship in New York City, and upon completion in August, I will be actively seeking full-time data scientist positions. My goals include applying robust analytics techniques to challenging real-world problems and impacting business strategies via actionable insights and data products. Skills: • Solid background in probability and statistics. Experience in experiment design and analysis (hypothesis testing). • Predictive modeling via various machine learning techniques (multivariate linear regression, lasso, naïve bayes, logistic regression, random forests, gradient boosted trees, neural networks, support vector machines). • Solid understanding of relational algebra. Experience in writing and interpreting complex SQL queries using open source relational databases (MySQL). • Mining and building predictive models on large sets of complex, high-dimensional and noisy real-world data. • Good understanding of computer science fundamentals (e.g. algorithms, data structures). Languages: Fluent in Python, SQL and MATLAB. Proficient in R and C++. Tools: MySQL, Pandas, SciPy, Scikit-learn, IPython notebook, Unix shell, Hadoop Streaming, Git, NLTK, Flask, AWS. Side Projects: • Created a novel filter for improving loan approval decisions at LendingClub, yielding an increase in overall ROI from -2.4% to 4.0% which corresponds to a net gain of ~15 Million USD. • Developed a model to forecast bike availability in Capital Bikeshare, predicting the number of bikes rented with predicted R-squared = 0.86. • Developed a movie recommender on Amazon Instant Movie review data using a weighted Slope One algorithm. GitHub: @ • Produced a deliverable in three weeks for an online microlending nonprofit in the form of a predictive model that is utilized for determining a flat fee (per country) upon the disbursement of a borrower’s first loan. The flat fee is to replace the traditional interest on loans. • Processed and manipulated data from tables in a MySQL database. The features used in downstream analysis and modeling were engineered after cleaning and processing the data in Pandas data frames. • Applied various machine learning techniques (e.g. ElasticNet, Logistic Regression, Random Forest) to predict defaults (recall=0.71 precision=0.78 on validation set) and loss from defaults (predicted R-squared = 0.70). The model yielded an average error (over 4 countries) of only 2.3% in total loss prediction, which is the ultimate point estimate to be used in flat fee determination. • Created an interactive front end using Flask and Twitter Bootstrap and deployed it on Amazon Web Services. From June 2015 to Present (7 months) Greater New York City AreaResearch Assistant @ Developing high-resolution MRI acquisition and reconstruction techniques for accelerated cardiovascular and musculoskeletal imaging in the Medical Imaging Laboratory. • Design, simulation and implementation of non-conventional image acquisition methods. • Estimation of missing image domain and spatiotemporal frequency information via multivariate regression and dimensionality reduction. • Image reconstruction using compressive sensing • Noise suppression using regularization (e.g. ridge regression, elastic net) • Low-latency real-time image reconstruction using multi-threaded hybrid CPU/GPU servers. • MRI sequence development for eddy current artifact removal Related Grad-level Courses • Matrix Analysis and Linear Algebra • Learning Theory • Random Signals Analysis • Computer Vision • Image Processing and Analysis | & || • Compressed Sensing MRI From August 2008 to May 2015 (6 years 10 months) Undergraduate Researcher @ Developed a clinical pipeline for the utilization of Diffusion Tensor Imaging in functional MRI at the Hacettepe University Hospital. From August 2007 to May 2008 (10 months) Intern @ Designed and implemented a graphical user interface for the Jamming Effectiveness Calculator in V/UHF Range. From June 2007 to July 2007 (2 months) Intern @ Started the design of the Inter-RF Subsystem Interface Protocol, working in a team reporting to senior engineers in the Communication Devices department. From June 2006 to July 2006 (2 months) Doctor of Philosophy (PhD), Biomedical Engineering @ The Johns Hopkins University From 2008 to 2015 Bachelor's degree, Electrical and Electronics Engineering @ Bilkent University From 2004 to 2008 Ozan Ph.D. is skilled in: Matlab, Signal Processing, Algorithms, Biomedical Engineering, MRI, Machine Learning, C++, Medical Imaging, CUDA, R, Mathematical Modeling, Computer Vision, Python, Data Mining, Regression Analysis
