plug n’ care Competition winner for Equity & Social Justice Our entry proposed modular housing constructed from fiber reinforced polymer (frp). This solution aims to involve the underserved community in the construction and development of the site. We visited and spoke to community members in Skid Row, Little Tokyo and West Adams and used their input in the design. The design responds to issues such as lack of healthcare facilities for the underserved, poor sanitary stations and a shortage of job opportunities for the homeless.

COMMUNITY INTERVIEWS We need more psychiaric and mental health therapists. The community needs basic first aid kits for animal bites.
We need hygiene, laundry, showers and proper shelter. People are overworked and burnt. When poeple dont have jobs, they do drugs.
Designers need to involve the community in the work and provide them with jobs. I dont like used clothes given to me.

There is a lack of safety, people killing straight out of prisons. We need to give job oppurtunity to the homeless.
We need more doctors and jobs for the homeless. We need to educate the community about healthcare. Perhaps more community and religious centers.
I lost a $39/hr job, and had my tent stolen. There are long lines for healthcare centers. We need sweaters, socks and rain ponchos.

loca Low Carbon Concrete Master’s Thesis As part of a 100 page thesis research, I explored parametric methods to reduce the quantity of concrete in a precast panel, hence proving one method in reducing the embodied carbon in concrete. I parametricized the conventional bubble deck slab on grasshopper, and used a combination of Python, sin formulas and Galapagos, to find the optimal reduction in cement while still maintaining structural strength.

Similar to conventional bubble deck slabs, the spheres inside the panel are arranged in a uniform fashion, with a control spacing between each sphere, and a 5mm distance from the bottom and top. Next year, the student panels will be attached to a shipping container to display the different types of concretes.

Galapagos for Grasshopper was used to optimize the sphere sizes and the cement reduction. I added attractor points using the Pop2D node on GH, and then connected columns to them to simulate real-life stress points. Next, I remapped the circle values based on where the stress points are and lastly colorized them based on a stress gradient.

DESIGN PROCESS
FINAL MODEL Since the overall form was beginning to look like an origami installation that folds, I removed the concrete base and continued the folds all the way to the bottom. I decided to design the project parametrically so that I could have control over the length, width, height and thickness of the bench via the program menu. I then created a model using brass, where I added brakes in the metal to replicate the folds in the design. Brass was used because it is more flexible then steel and less brittle then aluminum. After releasing the clamps, I realized I would need to further reinforce the corners using triangles on the corner, which would support the lateral loads. With the second reinforcement in place, I was comfortable to remove the clamps and see if the form holds up. With the second reinforcement in place, I was comfortable to remove the clamps and see if the form holds up. In order to transport the bench to the studio space two 2x4’s were placed at the bottom to lift the form.

JOINT DETAIL
FINGER JOINTS To give the corners both structural and aesthetic qualities, I decided to use finger joints to join the edge. I began by testing my joints on a small piece of wood. Then I sanded the edges to get a curved corner. After testing the idea, I began to make the joints on my main panels, with 2 inch teeth instead of the 1 inch used in the proof of concept.
FULL SCALE MODEL IN USE
Since my joints were done by hand, I realized that not all the edges lined up perfectly, therefore I had to improvise and use small wooden pieces in the gaps, with wood glue and epoxy to deal off all the holes and structural weaknesses in the corner.

oculus A GFRC Study using Revit and Dynamo To get a better understanding of GFRC as a material, I studied the KAFD Metro Station by Zaha Hadid in Riyadh. I translated the geometry in Revit by using RhinoInside. I was able to control the shape, structural connections and dimension of the geometry through Dynamo. Last, I casted a sample of the project using CNC foam milling and GFRC. Date: April 2021 Professor: Karen Kensak Course: Theories of Computer Technology (ARCH 507)

echological landscape Redeveloping a Waterfront in Busan For an international student competition, my team members and I decided to remove the existing warehouses and propose a landscape to encourage circulation and public gathering in the densely-populated area. The project invites a new dimension of color to a site that lacks any light. It uses a variety of textures in the landscape and artificial lighting around the curves, resulting in a valley that emits color during the day and night. Each group member was assigned a different task to complete. I was in charge of the site plan and diagrams, while Jun-sin made the render and Bae-Dahye put together the competition board.

VIEW OF BRIDGE
This part of the landscape features an artificial shore and a seating area, allowing visitors to relax and enjoy the water
The largest area of the site is also the highest in terms of elevation. The space is open to host musical performances and installations
The main attraction of the site is the pavilion that features a number of wind-chimes hanging from the rim. The pavilion provides visitors with an interactive art piece, and a shaded area to escape the heat of the sun.
The bridge is an important channel, used by people to walk across the city center to the main train station in the mall.

MAGNETIC HINGE SYSTEM
ATTACHING ROOF TO ROOF
The detachable magnetic hinge system introduces a magnetic hinge device designed for use with two objects that are not attached and yet need a turning movement between them, thus providing full flexibility in placing them with increased function and efficiency.

As the detachable magnetic hinge system always works as a body with any objects that require hinges, it is almost invisible and, therefore, is attractive looking. It is also efficient because it has temporarily detachable benefits at any time for convenience. The more efficient and economical benefits of magnetic hinges applied to various equipment used in industry and our daily lives are twofold: We can have more practical and attractivelooking daily goods with this new invention. Therefore, it is an invention that is economically rewarding.

The wooden poles are easily manufactured in nearby factories, and can be assembled on site.
They exhibit good mechanical characteristics, easy process ability, and conformability for use in structural components. Woven textiles allow easy production processes, even for complicated shapes, and they carry the possibility to design properties with different orientations. Their properties are more balanced compared to unidirectional fiber reinforcements. Their ease of handling, low fabrication cost, good stability, balanced properties, and excellent formability make the use of woven fabrics very attractive for structural applications

abstracting the technical Competition winner for Equity & Social Justice As part of Harvard Design Discovery, we were asked to draw sections elevations and plans of one handheld object, one piece of furniture and one room of our choice. Starting in this hierarchal order of small to big allowed us to pay attention to more details as we drew. We combined all 9 drawings into two abstract composites that challenged the idea of scale, space and orientation. The technical drawings of these objects taught us to study each & every dimension in the design. Between all nine sets of drawings, it was important to allow each one to speak to the other by maintaining similar line weights, and hatching patterns. Date: June 2019 Instructor: Sampath Pediredla

FINAL MODEL
Reinterpreting two artworks in a spacial form The room is influenced by two themes in two artworks: “stillness” in the Persistence of Memory by Salvatore Dali and “turbulence” in The Starry Night by Vincent van Gogh. By manipulating the curves, I was able to evoke a sense of turbulence in the bottom floor with the undulating walls and a spiral staircase. In the upper floor, the lines on the walls straighten out and point the occupier towards the main view. Date: July 2019 Instructor: Sampath Pediredla
