Title: “How nanotechnology can save us and environment: Making it happen in a safe way”
Nanotechnology is offering wonderful opportunities to make most of materials around us much better. Nanoparticles can help us to produce energy in a more efficient and less harmful way. They can also transform the environment around us and help us to clean it. Nanotechnology is opening new and exciting world for our civilization and we are still only at the beginning of this fantastic journey. However, there are questions about how safe those small particles are, and whether there are ways to make them safer. This lecture will discuss examples of emerging frontiers in this area while attempting to outline challenges in nanotechnology field.

Title: "Optically chopped PIR sensor for occupancy detection"
Passive infrared (PIR) sensors are the current choice for occupancy presence detection in buildings. The sensors are popularly used for controlling lighting, heating and cooling based on occupancy. A major problem is that these PIR sensors only detect individuals who are moving, which may provide false negative detections and inaccurate occupancy estimation, resulting in uncomfortable lighting/temperature swings, short lifetime of the equipment, and waste of energy. To address this issue, this talk presents a new type optically chopped PIR sensor, equipped with an electronic shutter and machine learning technologies that enable fast and accurate occupancy detection including individuals who are stationary.
Currently, the heating and cooling of buildings generates about 13% of the U.S. domestic greenhouse gas emissions and consumes about 40% of the energy used in a typical U.S. residence, making it the largest energy expense for most homes. When fully implemented, this technology can potentially reduce these emissions by two percentage points. Moreover, this technology can help U.S. businesses and residences eventually reduce reliance on tightly controlled building environments, thus enabling radical and sustainable architecture in next generation energy efficient building designs.

Title: “Extinction, extinction: How it was and how to stop it from the Miocene to today”
The central question of our time is whether we can manage global ecosystems to support us today and into the future, or we continue on current trends of ever-increasing extinction rates and ecosystem loss. But while many current challenges, such as massive carbon dioxide or nitrogen output, are unprecedented, others have in fact been unfolding for thousands of years. Here I show the results of studies combining the fossil record with DNA techniques to discover the footprint of human activities deep into the past. Using the islands of the Caribbean as a microcosm offers crucial lessons for the future: it would take nature millions of years to restore what was lost over only a few hundred years.

Title: “Computational Interaction in Post-PC Computing”
In the current Post-PC computing era, new computing technologies such as mobile computing, wearable computing, augmented and virtual reality have emerged, which bring wicked challenges to interaction between humans and information technology. To address these challenges, designers must consider a multiplicity of problems from low-level hardware, through software, all the way to human factors. In this talk I will introduce a new perspective, which was introduced in our recently published book Computational Interaction, on how to design software user interfaces and interaction technology. It is an approach that focuses on the use of algorithms and mathematical models to explain and enhance interaction between humans and information technology. I will particularly introduce how to apply this approach to enhance text-based communication on mobile and wearable devices, and solve touchscreen interface design problems.
