1PRIVATELY OWNED PUBLIC SPACENEW YORK, NY
This studio will bring forward the taxonomy of the performative tactics of existing corporate architecture to develop the strategies for a new Architecture of the Corporation that is an agent for new kinds of collaboration and cohabitation in the city. The goal of the studio is to investigate the possibility of architecture that is the catalyst for the coexistence of the market and the civic, the articulated and productive interface between the ideals of the city and the means that support it, and generate a projection for an urban infrastructure against the obsolete or irrelevant (non)cities of the future.
Through research of Privately Owned Public Space (POPS) in New York City, this project sought to develop and design a new POPS system within the city. Using Hudson Yards as a case study, this system was deployed across the development. By connecting and programming each space to have a different function, and creating a brand identity to make the spaces easily recognizable, the new POPS system aims to become a vital part of the development and attract users from across the city with its varied and diverse programming.

2NATIONAL SPELEOLOGICAL SOCIETY HEADQUARTERSCAVE CITY, KY
To locate a site, create a program, and design a new headquarters for the National Speleological Society. This project should take into consideration the goals of the group, including visibility, current member needs and membership growth, as well as budget. At the end of the semester, the research compiled by the studio, as well as the individual projects will be sent to the NSS for their use.
The new headquarters design was located in Cave City, Kentucky, near the Mammoth Caves, and in the heart of the caving culture. The design incorporates a museum, archives, sleeping quarters, and a meeting room to allow the building to function in all necessary capacities, while remaining small in size to accommodate the modest budget of the NSS.

3PAPER ARCH
This project explored, through the production of a freestanding arch, the various ways in which complex assemblies are drawn, described and fabricated, with comprehensive directions for final assembly. Each team selected an assembly system, made up of a limited number of varied and related units, to examine communication techniques of diagramming 2D + 3D and production of coordinated sets of directions for making and assembly.
Together with my partner, Minghue Huang, we researched, designed and constructed a full scale arch out of Bristol paper, to a height sufficient for the professor (5-7) to walk under freely. The arch was composed solely of the designed units, with no separate connection pieces or adhesive. Drawings were out together as an instruction manual, describing through drawing, the method of assembly to construct the arch in full.

PROJECT DESCRIPTION AND OBJECTIVES:
The intention of this exercise is to begin to explore techniques and logics of variable assemblies through iterative research methods that integrate parametric and scripted computation strategies and scale model fabrications. Explorations should follow an iterative process through a series of intense and focused explorations of specific material(s)/method(s).
PROJECT DESIGN:
This surface is derived from strips of paper that are folded and joined in a series of simple operations to produce a larger unit; these larger units then aggregate to form a surface. These operations create surface that act as a screen, with the units aggregating along a curving surface, the length and dimensions of each strip change in accordance to its position in the structure. To allow the unit to aggregate along the curving the surface, the script offsets from a selected surface, and the projects normal to that surface a specified distance to form each unit. To affect the depth of the unit, an attractor point, changes the depth of the unit based on its distance from the attractor point.

5BIOFUEL PRODUCTION
Each group will prepare and produce an illustrated narrative text that frames, links, explains, expands, etc. the stories of the particular industrial sector they have been examining within the Great Lakes Mega-Region.
Together with Sheri Zon, our research analyses the production of the two leading biofuels in the Great Lakes Mega-region: corn-based ethanol and biodiesel made from soy. The support of biofuel through government incentives, laws and regulations, and programs for ethanol and biodiesel production in the last decade is a response to environmental concerns and the United States ever-increasing consumption of non-domestic fossil fuels. This analysis examines what is driving the biofuel industry, the inputs/outputs/byproducts/volumes of its production, the expanse of its distribution, its impacts on connected markets, and its potential for continued growth in the Great Lakes Mega-region.

This thesis will focus upon ways through which architecture converts abstract cultural notions about the world into physical forms that engender them with the characteristics of real things. It will examine different ways that belief becomes inscribed in spatial orderings, and explore architectures role in smoothing over apparent contradictions between the concepts with which we define the physical world and the way we experience it through our senses. This thesis will call into question the terms and techniques with which architecture embodies and communicates different views, values, and cultural mythologies and it will experiment with techniques for making things that adhere to contradictory types of conceptual and visual logic simultaneously.
This thesis explores the ways in which perceptions of distance can be manipulated, and works to simultaneously exaggerate and collapse ones sense of distance within a single spatial envelope. Through investigations into physical, visual, material and experiential means of spatial manipulation, such as the international dateline, geographical mapping techniques, and cultural borders, this work creates two simultaneous perceptions of reality that interact with, and are cognizant of each other.
