It’s My 10 Year Blogging Anniversary!

Woohoo, it’s already ten years since I started this blog. Can’t believe it! Thanks to all of those who read my posts, and who encouraged and inspired me. Without you blogging would be only half the fun! Now, let’s have a little recap…

2007-2009 SAP and India:

It all started in 2007. I was studying Computer Science, and decided to go for an internship abroad. China and India were on my short list. I decided for India, applied for a scholarship and asked some companies for interesting project work. Before starting the adventure, I published my very first blog post to keep family and friends in loop.

For the next seven month, I lived in Bangalore, and worked for SAP Labs India to develop prototypes for mobile BI apps. I spent plenty of weekends to explore India and surrounding countries. After returning from India, I continued to work for SAP at their headquarters while finishing my degree in Karlsruhe.

2009-2012 CERN:

CERN, surrounded by snow-capped mountains and Lake Geneva, grabbed my attention during the end of my studies. CERN has tons of data: some petabytes! Challange accepted. CERN is known for its particle accelerator Large Hadron Collider (LHC). We applied machine learning to identify new correlations between variables (LHC data and external data) that were not previously connected.

2012-2015 Capgemini and MBA:

Back in Germany, I wanted to bring Big Data Analytics to companies. To one company? No, to many companies! So instead of getting hired as Head of BI for an SME, I started to work for Capgemini. I had fantastic projects, designed data-driven usecases for the financial sector, and gave advice for digital transformation inititives.

In order to keep in balance with all the project work, I dedicated many of my weekend for studies and got enrolled in Frankfurt School’s Executive MBA programme. During my studies, I focused on Emerging Markets and visited a module at CEIBS in Shanghai.

2015-201? Tableau and Futura:

I knew Tableau from my time as consultant. It is an awesome company with a great product and a mission: help people see and understand their data. That’s me! I joined Tableau to help organizations through the transition from classic BI factories to modern self-service analytics by developing data strategies, so that data can be treated as a corporate asset. This includes education, evangelism and establishing a data-driven culture.

In the evenings I’m working for Futura Analytics, a fintech startup, which I co-founded in 2017. Futura Analytics offers real-time information discovery, and transforms data from social media and other public sources into actionable signals.

What’s next?

Currently I’m looking forward to give my Data Strategy talk on TC17 accompanied by a TensorFlow demo scenario. I’m also learning Mandarin, the predominant language of business, politics, and media in China and Taiwan, for quite a while. Let’s see if that is going to influence my next steps… 🙂

How to unleash Data Science with an MBA?

My Data Science journey starts at CERN where I finished my master thesis in 2009. CERN, the European Organization for Nuclear Research, is the home of the Large Hadron Collider (LHC) and has some questions to answer: like how the universe works and what is it made of. CERN collects nearly unbelievable amounts of data – 35 petabytes of data per year that needs analysis. After submitted my thesis, I continued my Data Science research at CERN.

I began to wonder: Which insights are to be discovered beyond Particle Physics? How can traditional companies benefit from Data Science? After almost four exciting years at CERN with plenty of Hadoop and Map/Reduce, I decided to join Capgemini to develop business in Big Data Analysics, and to boost their engagements in Business Intelligence. In order to leverage my data-driven background I enrolled for the Executive MBA program at Frankfurt School of Finance & Management including an Emerging Markets module at CEIBS in Shanghai.

Today companies have realized that Business Analytics needs to be an essential part of their competitive strategy. The demand on Data Scientists grows exponentially. To me, Data Science is more about the right questions being asked than the actual data. The MBA enabled me to understand that data does not provide insights unless appropriately questioned. Delivering excellent Big Data projects requires a full understanding of the business, developing the questions, distilling the adequate amount of data to answer those questions and communicating the proposed solution to the target audience.

Goodbye Academia, Hello Capgemini

I have enjoyed research for the last four years. Yet, I have decided to resigned from my postgraduate position at CERN, and to move to Capgemini. I will continue on the areas I love: Data and Analytics!

Capgemini is one of the world’s largest consulting corporations. Like many other consulting company, Capgemini does not yet have a dedicated team to offer effective strategies and solutions employing Big Data, Analytics and Machine Learning.

I love these technologies, and I am very confident that I will elaborate a business development plan to drive business growth, through customer and market definition, including new services such as:

  • Data Science Strategy (enable organizations to solve business problems increasingly with insights from analytics)
  • Consulting (answering questions using data)
  • Development (building custom data-related tools like interactive dashboards, pipelines, customized Hadoop setup, data prep scripts…)
  • Training (across a variety of skill levels; from basic dashboard design to deep dive in R, Python and D3.js)

This plan is also accompanied by a go-to-market strategy, which I don’t want to unveil on my blog. Maybe retrospective in some years, so stay tuned…

Physics projects don’t get any bigger than this. The active European Organization for Nuclear Research, aka CERN, formed in 1954 and is headquartered in Geneva, Switzerland, employs thousands of world-class scientists on the forefront of breakthrough research. Its claim to fame is unmatched as the origin of the World Wide Web and creator of underground 17-mile-long particle accelerator called the Large Hadron Collider. Here, see photos of the many aspects of an international institution that may discover a way to move faster than the speed of light and how our universe was pieced together.

Challenges of Big Data Analytics in High-Energy Physics

Challenges of Big Data Analytics: volume, variety, velocity and veracity

There are four key issues to overcome if you want to tame Big Data: volume (quantity of data), variety (different forms of data), velocity (how fast the data is generated and processed) and veracity (variation in quality of data). You have to be able to deal with lots and lots, of all kinds of data, moving really quickly.

That is why Big Data Analytics has a huge impact on how we plan CERN’s overall technology strategy as well as specific strategies for High-Energy Physics analysis. We want to profit from our data investment and extract the knowledge. This has to be done in a proactive, predictive and intelligent way.

The following presentation shows you how we use Big Data Analytics to improve the operation of the Large Hardron Collider.
