LANDSCAPE ARCHITECTURE | PORTFOLIO
A designer of the Anthropocene Urban areas contain a profusion of invisible landscapes â€“ landscapes filled with complex interactions waiting to be explored and unraveled. Through my designs, I explore the revelation of these terrain vagues and the processes that lie within them. We belong to the epoch of the Anthropocene - the earthâ€™s human age, where we are the ecosystem, and designing for adaptation to change is exigent. I look forward to creating designs that rethink the conventional definition of nature. I believe creating rambunctious urban landscapes that dissolve the dichotomy of man and nature while revealing and celebrating ecological and cultural processes is the way forward.

weed ecologies Semester IV Birmingham, Alabama
Studying novel ecosystems is important because they exist in cities - which is home to an increasing fraction of humanity and, hence most peopleâ€™s experience of nature is urban. â€˜Weed Ecologiesâ€™ is a designed experiment that aims at providing opportunities to study the process of the growth and succession of novel ecosystems and, the processes of species that lie within them. The terrain vagues of Birmingham, having been altered in structure and function by human agency, are brimming with novel ecosystems. Opportunity for studying the patch dynamics of these terrain vagues is achieved by merging traditional study practices of transects with novel ecological landscapes. Additionally, inviting locals institutions to study, experience and research these patches can provide opportunities to learn, to understand, and love spontaneous wild urban species. 1

Invasive Plants Can Create Positive Ecological Change “Nature is in a constant state of flux, always readjusting as new relationships form between species, and not all of these relationships are bad just because they are novel or created by humans” -Thomas Carlo
Terrain Vagues of Birmingham Birmingham, a post industrial city has high percentage of tax delinquent properties. The older tax delinquent properties have rich weed ecologies because they have been vacant for a long time.
Terrain Vagues as Designed Experiments These older tax delinquent properties that lie within the floodplain are selected to perform as designed experimental labs for studying the ecological and aesthetic potential of novel ecosystems.
The ecological potential of each of these vacant sites is studied as a typological matrix.(Left) and short listed sites are analyzed based on their strengths.(Below) Site no. 3 is selected as proposed site.
SITE NO 1 Vegetated Along Valley creek Access to under bridge ecosystems Larger than an acre Few buildings on site Potential to merge several TDPâ€™s Access to creek side ecosystems
SITE NO 2 Moderately vegetated Along Valley creek Easily accessible from urban core Larger than an acre Site is cleared of buildings Access to creekside ecosystems

Bricks, mounds, and mills Studio III Lagrange, Georgia ATLANTA
The Hillside community located in Lagrange, GA was founded in 1915 as a 275 acre mill neighborhood. When the mills ownership changed hands, housing was no longer affiliated with the mill and the residents had to travel large distances to get to work. This led to the disinvestment and deteriorating condition of the neighborhood. In this studio, the Auburn University Masters of Landscape Architecture spring 2017 studio, worked with the non profit DASH and the community to design proposals for sustainable economic solutions to improve the conditions of the neighborhood. This proposal for Hillside park focuses on four key issues â€” Recreation, Infrastructure, Safety and most importantly Identity of the neighborhood.

Community and context
Community Engagement and Pop-up Park Involving the community helped gain multiple perspectives of the site and helped residents gain ownership of the design process. Additionally, the pop up park helped the community understand how a small under utilized urban space can be re-imagined or re-purposed with little materials and budget.

Mill houses and Hillside park
A view of mill houses overlooking hillside park with minimal infrastructure. The community enjoys the trees on site and aims to preserve them.
Proposed section for Hillside park
The proposed section combines hard edges of bricks (borrowed from the millâ€™s texture) and soft edges of lawn mounds to create pockets of recreational interest. It also preserves most of the existing trees on site.
Path for people
Path for water
Movement of people and water through site
People experience flow of water on a parallel path. The site allows for rainwater from the neighborhood to flow through the site.
A, B, C
Recycling water through Hillside
Water is slowed down using moss walls(A).The water then flows through a culvert(B) and is purified using a rain garden(C). The water is then collected and pumped up to irrigate neighborhood landscapes(D).
PLAN OF BRICK LAYOUT
Texture found on site
This brick wall is designed to slow down water and to facilitate the growth of moss which cleans the water further before it drips into the rain garden.

fall line Park Studio II Columbus, Georgia ATLANTA
The fall line is a geomorphic break that separates the Piedmont from the Coastal Plains. At Columbus, the fall line is a place where the Chattahoochee River plunges creating interesting geologic features like rapids and islands. This park design creates an urban cultural space for people at various scales (personal, small gathering, large gathering). It is a space where people can learn, interact with and experience some of these interesting geological and ecological conditions the Chattahoochee creates.

Pattern Nerve Fibers
Fall line park : Formal Inspiration
Research on three types of fibers — living, natural and synthetic suggests that the word ‘Fibrous’ can be generally categorized to have common characteristics of length, connection, pattern, stretching, flexibility and porosity — elements i wanted to include in the park design.
Material Exploration and Iterations
Study model iterations (top) work in one characteristics of the word fibrous â€” Connection, Stretch, Length, Porous, and Pattern. Hybrid models (right) further integrate many characters of fibrous into one model.
Further material explorations with digital fabrication
The plaster models were digitalized using photogrammetry software (123D Catch) and iterations were modelled by laser cutting cardboard and CNC milling foam. These models were not as rigid as the plaster model but they are more simplistic.
Digital remix models
Each module is arranged to look organic and dynamic, having different parameters of size and height, thereby making it look less rigid.

PA R K PEOPLE
Park for People
The Fall Line park is a place where people can learn about process and interact with the Chattahoochee River water. The park uses multiple scales and hierarchy of park spaces.
Space for large groups
The central zone is open and can be used for large gatherings like concerts and as a large playground.
Space for small groups
The Muhly grass and the grove of trees bind spaces to create zones comfortable for small group gatherings.
Personal space at the park These small stepped seats by the river are designed to be personal spaces. The three sizes of steps can host one to five people in one module. Low water condition allows for growth of wetland plants and more space for people to interact with the river. Illustration on the project introduction page shows high water conditions embracing sediment deposition and flooding.

The didactic surface Semester II Plant Spatiality
The word â€˜didacticâ€™ in the context of landscape architecture implies participatory action - a response or dialogue between a visitor and a landscape. In this project, the experience of moving through different widths of pathways surrounded by varied heights of grass, helps visitors perceive and experience wind patterns and movement on site. Taller grasses hide the view of the river and visitors have to gradually move down the slope of the site to be able to see the water. Additionally, open decks strategically placed at the edge conditions of grass types(tall, medium and short), allows observers to notice grass moving and creating patterns from an elevation.
PLANT STUDIES Plant Ephemerality Plant Spatiality
Plant ephemerality - this project acknowledges and heightens the ephemeral spatiality of planted forms within a small garden as it transitions through time. The design advances the exploration of plant phenology by highlighting the spatial and textural qualities of a specific plant palette changing through the seasons of an entire year. Plant spatiality - Quick on-site sketches of commonly found plant species of Alabama. Drawing these species helped with learning to identify plants and to observe their spatiality and habitat.
FIELD STUDIES Minneapolis Birmingham
Gathering information about landscapes, sites, and designs through sketching. The process of recording and documenting these sketches helps capture the essence and structure of designs to gain a better understanding of a space. Observing and drawing construction details helps gain more knowledge on site.
